FOMO (fear of Missing Out): What it Is, Causes, Symptoms and Treatment

It’s Saturday night, you’re on the couch in clean pajamas, and you picked this evening on purpose. Then the phone lights up: a friend’s story, six faces squeezed into a booth, someone mid-laugh with a drink the color of a traffic cone. Your chest does something small and sour. The soup you were enjoying ten seconds ago now tastes like a decision you regret. You scroll for four more minutes, then twenty, and by the time you put the phone down, the quiet evening you chose has been quietly rewritten as the evening you got left out of.

That sour little drop has a name, and it’s more common than most people admit: FOMO, or the fear of missing out. In its mild form it’s a flicker. In its stubborn form, sometimes called FOMO syndrome online, it becomes a steady belief that other people’s lives are more interesting than yours, and that every choice you make is costing you something better happening elsewhere. It follows you into dinners you enjoy, jobs you chose and relationships that are, objectively, fine.

It isn’t weakness. It’s a very human alarm, wired to a very modern amplifier.

This guide explains what FOMO is, its causes, symptoms and treatment, answers the question “how do I know if I have a FOMO problem?”, and shows what the research really says about feeling that everyone else is having a better time.

Expect honest limits too, and a few small experiments you can run tonight. The evidence is largely correlational, the label isn’t a diagnosis, and a few popular claims don’t hold up well.

What is FOMO, and where does the term come from?

FOMO is a pervasive apprehension that other people might be having rewarding experiences from which you are absent. It comes with a desire to stay continually connected with what others are doing. That is the working definition used in psychology research, and it covers more than parties: jobs, trips, news, trends, even opinions.

The idea moved from slang to science in 2013, when psychologist Andrew K. Przybylski and colleagues published a study in Computers in Human Behavior that defined FOMO and built a measure for it, the Fear of Missing Out Scale, a 10-item questionnaire. Across their studies, people higher in FOMO tended to have lower satisfaction of basic psychological needs, lower general mood and life satisfaction, and heavier social media engagement, including use at inconvenient or risky moments such as during meals, lectures or driving.

Notice that the scale measures a trait, a tendency to feel this way, and a state, how you feel right now. Everyone has the state occasionally. Some people carry the trait around like a second shadow.

FOMO has two intertwined parts. The first is apprehension, a worry that something better is happening. The second is compulsive checking, an urge to stay connected so you won’t miss anything. The checking offers brief relief and, typically, a fresh prompt for the worry. Over time the loop tightens.

Consider Jordan, 24, in a shared house with three roommates whose group chat never sleeps. Jordan stays up until 1 a.m. reading messages about a plan that he decided, hours earlier, he didn’t want to join. The plan was never the point. The not-knowing was.

It also helps to separate FOMO from ordinary regret. Regret looks backward at a choice you made. FOMO looks sideways, at lives running in parallel to yours, and forward, at what you might be forfeiting by choosing anything at all.

Is it new? The feeling is old; social animals have always monitored what the group is doing, because exclusion once carried real risk. What is new is the volume. Phones give a live feed of everyone else’s best moments, in your pocket, all day.

Is FOMO syndrome a mental disorder?

No. FOMO syndrome is a popular label, not a diagnosis. It does not appear as a disorder in the standard diagnostic manuals, and there is no official threshold at which “normal FOMO” becomes an illness. Researchers treat it as a psychological trait and a feeling that varies in degree.

Calling it a “syndrome” can mislead. It suggests a defined cluster of symptoms with a known cause and course, which FOMO lacks. What the research shows is a spectrum, from a passing pang to a persistent, distressing preoccupation, and a set of correlations with other things: anxiety, low mood, loneliness, problematic smartphone use and lower life satisfaction.

That matters for two reasons. First, if you feel FOMO often, you aren’t “diagnosed” with anything, and you shouldn’t feel you have a disease. Second, when FOMO is severe, it frequently sits alongside real conditions such as social anxiety, depression or generalized anxiety, and those are worth evaluating in their own right.

A related concept is problematic smartphone use, where checking becomes hard to control and starts interfering with work, sleep or relationships. FOMO is one of the factors linked with it. Neither is an official diagnosis, though gaming and other behavioral addictions have received more formal attention.

The honest summary: FOMO is a useful descriptive concept, a measurable feeling and a hint that something in your needs, habits or environment deserves attention. It isn’t a verdict about your mental health.

A fair question follows. If it’s not a disorder, why do so many people say it wrecks their evenings? Because disorder status isn’t the same as distress. A gnawing sense of being left out can hurt without meeting any clinical threshold, in the same way that a bad back can hurt without being a diagnosis of a spinal disease.

Think of it as a signal light on the dashboard. Sometimes the light means “check the tire,” sometimes the sensor is sticky. Learning which is which is part of the work.

What causes FOMO?

The best-supported explanation is unmet psychological needs. Andrew K. Przybylski‘s team drew on self-determination theory, developed by psychologists Richard M. Ryan and Edward L. Deci, which proposes that people have three basic psychological needs: autonomy (acting from your own choice), competence (feeling effective) and relatedness (feeling connected to others). When these needs go unmet, well-being suffers, and people look for ways to compensate.

In Przybylski’s 2013 studies, people with lower satisfaction of these needs, especially relatedness and competence, reported higher FOMO. The reading is that FOMO may act as a bridge: if you feel disconnected, you monitor others’ lives closely to stay in touch, and the monitoring brings its own pangs. The data are correlational, so they can’t prove which causes which. Feeling left out can raise FOMO, but FOMO may also lead you to engage in ways that make you feel more left out.

Several other contributors are plausible:

Social media design. Platforms deliver a continuous stream of other people’s highlights, with notifications that reward checking. Personal traits. Anxiety, perfectionism, low self-esteem and a strong need for approval are all associated with higher FOMO. Life stage. Transitions, such as starting university, moving cities or changing jobs, loosen your social anchors and make comparison more tempting. Culture and values. Environments that prize constant activity, networking and “living your best life” teach people that rest is falling behind.

Early experiences may matter too. People who learned to equate being included with being valued, or who experienced bullying or exclusion, can be especially sensitive to signs of being left out. Evidence here is thinner, and it’s best treated as a hypothesis.

Here’s an interesting wrinkle. FOMO isn’t only about missing something that exists. It can arise from imagined alternatives: the life you didn’t choose, the career path you passed on, the city you didn’t move to. In that sense it’s close to the old human problem of “the grass is greener,” made vivid by screens.

Picture Meera, 31, content with her job at a nonprofit until a college friend posts about a startup launch in another country. Within days she is rereading her own contract as a cage. Her job hasn’t changed. Her sense of relatedness and competence has been jostled by a stranger’s good news.

The practical takeaway of the needs model: FOMO is often a flag for something missing in your own life, such as connection, mastery or choice, not just a reaction to other people’s posts.

Why do other people’s lives always seem more interesting than mine?

Because you’re comparing your whole life, behind the scenes, with their edited highlights. Psychologist Leon Festinger proposed in 1954 that people have a drive to evaluate their opinions and abilities, and that when objective standards are missing, they do it by social comparison, measuring themselves against other people. Upward comparison, against those who seem better off, tends to prompt feelings of inadequacy.

Social media supercharges the mechanism. You rarely see anyone’s Tuesday spent waiting at a bus stop or an argument about the dishwasher. You see the beach, the promotion, the engagement ring, the packed table. Each person curates, and the sum is a feed in which everyone else seems to live in a permanent montage. Your own life, seen from inside, includes the boring parts in full resolution.

Research on the cost is suggestive, with limits. A widely cited 2013 study by Ethan Kross and colleagues followed young adults for two weeks with text-message prompts and found that more Facebook use predicted declines in how they felt moment to moment and in their life satisfaction over time. The study didn’t show that Facebook was the only cause, and later work has found small and mixed effects of social media on well-being, so the overall picture isn’t a simple “social media makes you miserable.”

Nuance helps. Passive use, scrolling and watching, appears to be associated with worse outcomes than active use, such as chatting with friends. The comparison is the active ingredient: seeing people’s lives and measuring yours against them, without interaction.

There’s also an illusion of density. In any friend group, the story is often that everyone is together all the time, when in truth different subsets meet at different times, and you’re seeing them all at once. A week of other people’s gatherings appears in a single scroll, compressed.

Consider Tobias, 58, recently retired, who sees photos of former colleagues at a conference and feels a pang of exile. The conference days were tedious. He knew that when he worked there. His mind skips that part.

A question to carry: when you feel the pang, are you comparing against a real life or against an advertisement for one?

What are the symptoms of FOMO?

They show up as thoughts, feelings, behaviors and sometimes physical signals. FOMO isn’t a diagnosis, so there is no official symptom list, but researchers and clinicians consistently describe a set of recognizable patterns.

• Compulsive checking of phones, feeds and group chats, often with a restless urge you can’t quite resist.
• Persistent comparison, with a running sense that others are happier, more successful or more included.
• Difficulty enjoying the present, because part of your mind is elsewhere, wondering what you’re missing.
• Saying yes when you mean no, overcommitting to plans to avoid being left out.
• Anxiety or low mood after scrolling, such as irritability, envy, or a flat feeling that wasn’t there before.
• Trouble sleeping, particularly late-night scrolling “just to see” what’s happening.
• Indecision, since every choice feels like closing a door on a better one.

Some people also notice physical sensations: a tight chest, a knot in the stomach, restlessness, a pounding heart when a message goes unanswered. These are common with anxiety generally.

Behavior patterns provide more clues than feelings alone. People with higher FOMO tend to check their phones within minutes of waking, use them during meals or conversations, and find it hard to put them away. In the work of Andrew K. Przybylski, FOMO was associated with using social media at inappropriate moments, including while driving or during lectures.

It also affects relationships. Being “present but not present” can wear on partners, friends and children, who notice the glance at the screen. Ironically, the pursuit of connection online can erode connection offline.

Notice what is not on the list: enjoying a rich social life, being curious about others or wanting to attend events. FOMO involves anxious pursuit and a sense of lack, not simple interest.

Take Priya, 27, who accepted three weekend invitations she didn’t want. She spent Saturday rushing between them, answering messages in the taxi and feeling vaguely unwell. On Sunday she could not name a single moment she’d enjoyed. She had attended everything and experienced nothing.

How do I know if I have a FOMO problem?

Look at how much it costs you. Everyone feels FOMO sometimes; the question is whether it is frequent, hard to control and damaging to your mood, time, money, sleep or relationships. No quiz can diagnose it, but a few honest questions give a decent picture.

Ask yourself these questions, and notice how many get a yes:

Do I check my phone first thing and last thing? Do I feel uneasy or irritable when I can’t see what others are doing? Do I say yes to events I’d rather skip? Do I feel worse about my life after scrolling? Do I struggle to enjoy things I’m doing because I’m thinking about other options? Has anyone close to me commented on my phone use?

Several yeses over several weeks suggest it deserves attention. The research version is the Fear of Missing Out Scale, which asks people to rate statements such as how anxious they feel when they don’t know what friends are up to. It is a research tool, not a clinical test, and a score doesn’t tell you whether you “have” a problem. It does give a rough sense of where you fall compared with other people.

A more useful measure is functional. What is it costing? Hours? Sleep? Money spent on events or travel you couldn’t afford? The ability to be present with someone you love?

Try this experiment for a week. Note each time you feel the pang, what triggered it and how long it lasted. Many people discover that a handful of sources, certain accounts, certain group chats, certain times of day, produce most of it.

Imagine Carlos, 35, who tracked his pangs and found that nine of twelve came after one college friend’s travel posts. The finding wasn’t “I have a disorder.” It was “I need to mute one person.” That was enough.

How does FOMO affect mental health?

It is linked with more anxiety, low mood and problematic phone use, though the direction of cause is unclear. Studies consistently find that FOMO is correlated with these outcomes. What they don’t establish is whether FOMO produces them, whether distress produces FOMO, or whether a third factor drives both.

Researcher Jon D. Elhai and colleagues surveyed participants in 2016 and found that problematic smartphone use was most strongly related to anxiety, need for touch and FOMO. A later survey of 316 American undergraduates from the same research group found that FOMO helped link depression and anxiety to problematic smartphone use: FOMO mediated the relationship between depression and problematic use and between anxiety and problematic use. The authors suggested that for anxious or depressed individuals, heavy phone use may be a way of avoiding distress and meeting a desire for social connection, even while social anxiety makes real contact harder.

Notice the circularity. Anxiety raises FOMO, FOMO drives checking, checking exposes you to comparison, and comparison raises anxiety. Survey data like these capture a moment, not a chain of events, so the loop is plausible rather than proven.

Other effects reported in the literature include:

Poorer sleep, since late-night checking delays bedtime and the content can be arousing. Lower life satisfaction and mood. More loneliness, paradoxically, despite more online contact. Financial strain from spending on events, travel or purchases to keep up. And in students, distraction from study and a tendency to check phones during lectures.

It’s worth being cautious about causal claims. Many studies use self-report from students or young adults, and effect sizes tend to be small to moderate. The findings may differ across cultures and age groups, and some research suggests that FOMO is also linked with positive engagement, such as staying in touch with a community. Calling it simply “toxic” would overstate the data.

Imagine Dalia, 20, in a university dorm, who tracks her friends’ plans compulsively because she moved to a new city and doesn’t yet feel part of any group. The checking reflects her need for connection. It also makes her feel more left out each time. Her fix isn’t a better filter. It’s finding two people to see regularly in person.

When FOMO coexists with persistent sadness, hopelessness, panic or inability to function, treat that as a signal to look more broadly at mental health, not only at phone habits.

Why does having more choices make FOMO worse?

Because every option you choose implies options you didn’t. Psychologist Barry Schwartz and colleagues described in 2002 a distinction between maximizers, who try to find the best possible option, and satisficers, who accept an option that is good enough. In their studies, people scoring high on maximizing tended to report less happiness, optimism and life satisfaction, and more regret and depression, even though they often achieved objectively good results.

The link to FOMO is straightforward. If you must pick the best party, the best career, the best city, the best partner, then the options you did not pick become a constant source of “what if.” The more choices available, the more you can imagine a better one. Modern life and social media multiply choices and make the unchosen alternatives visible.

A caveat: the maximizing research relies largely on self-report scales, replications have been mixed on some effects, and a related claim about “choice overload” (that more options always reduce satisfaction) has been disputed in later reviews. The pattern appears more reliable for people who are prone to regret and comparison than as a universal law.

Still, the experience is familiar. You settle on a restaurant, then check three other menus. You accept a job, then read about someone else’s offer. You choose an evening in, then tour everyone else’s evenings.

The antidote has a name: satisficing, which means deciding on criteria in advance, choosing the first option that meets them and stopping the search. It’s not settling. It’s recognizing that the search has costs too, in time, attention and peace of mind.

Consider Yusuf, 40, deciding where to take a family holiday. He spends hours on reviews, finds something good, then keeps hunting for something better until the booking window closes and prices rise. The final trip is fine. The weeks of searching were not.

Try a simple rule for low-stakes decisions: three options, one criterion that matters most, a time limit. Decide, and then stop reading about the alternatives.

What treatments and strategies actually help with FOMO?

Because FOMO isn’t a diagnosis, there is no standard “FOMO treatment.” What helps is a mix of habit changes and, where needed, therapy aimed at the anxiety, comparison and avoidance underneath. The most direct evidence concerns cutting down social media use.

Psychologist Melissa G. Hunt and colleagues ran a randomized trial published in 2018. After a week of baseline monitoring, 143 undergraduates at the University of Pennsylvania were assigned either to limit Facebook, Instagram and Snapchat to 10 minutes per platform per day for three weeks, or to use social media as usual. The limited-use group showed significant reductions in loneliness and depression compared with the control group. Interestingly, both groups showed decreases in anxiety and FOMO from baseline, which the authors suggested might reflect the benefit of simply monitoring one’s use. The authors concluded that limiting use to about 30 minutes a day may improve well-being. Keep in mind the sample was small, all undergraduates at one university, and the follow-up short.

Here is a practical program that draws on that finding and on standard psychological approaches:

1. Measure first. Check your phone’s screen-time report for a week. Awareness alone reduced FOMO in both groups of Hunt’s study.
2. Set a daily limit. Thirty to sixty minutes for social platforms is a reasonable experiment, using built-in timers. Keep it for three weeks before judging.
3. Edit your feed. Mute or unfollow accounts that reliably trigger comparison. Follow some that make you feel informed or calm.
4. Challenge the thought. Using cognitive behavioral therapy techniques, write down the automatic thought (“everyone is having more fun”) and test it: what do I actually know? What are they not showing?
5. Practice acceptance of missing out. Borrowing from acceptance and commitment therapy, name the pang, let it be there and do the thing you decided was important anyway.
6. Build real connection. Schedule one in-person or voice contact per week. Because relatedness is a core driver, filling that need directly is likelier to help than filtering content.

Some people find reframing helpful: JOMO, the joy of missing out, describes deliberately enjoying your own choice. It can be a useful attitude if it isn’t forced; telling yourself to feel joy when you feel envy rarely works.

Values matter more than rules. Ask what you want your evenings, weekends and years to contain. When choices flow from those values, a missed event stings less.

Take Kenji, 33, who set a 45-minute limit, muted two accounts and began a Thursday walk with a friend. By week three he reported fewer “sour drops” and, more notably, less reaching for the phone in idle moments. The pang didn’t vanish. It stopped steering.

When should you seek help for FOMO, and who is most affected?

Seek help when FOMO is persistent, hard to control, and tied to anxiety, low mood, sleep trouble or damaged relationships that don’t improve with the strategies above. A therapist or licensed counselor can assess what’s underneath and offer structured help.

Signs that it may be more than ordinary FOMO:

• Distress that lasts weeks, such as persistent sadness, worry or a feeling of being fundamentally left out.
• Loss of control over phone use, with failed attempts to cut down and neglect of work, study or sleep.
• Avoidance of real contact because comparison or social anxiety makes people feel inadequate.

Therapy options include cognitive behavioral therapy for anxiety and social anxiety, acceptance and commitment therapy for relating differently to unwelcome feelings, and, where relevant, treatment for depression or problematic technology use. A primary care doctor can be a first stop if you have sleep problems or low mood. If you ever feel hopeless or have thoughts of harming yourself, contact local emergency services or a crisis line immediately.

Who tends to be most affected? Research has focused on adolescents and young adults, who are heavy users of social media and at a stage when peer belonging matters intensely. But FOMO isn’t confined to youth. Remote workers watching colleagues’ office banter, new parents seeing friends travel, people in midlife comparing careers, and older adults looking at grandchildren’s posts they aren’t part of can all feel it. Findings on gender and age are mixed, so beware of confident generalizations.

Parents can help young people by modeling their own phone habits, keeping bedrooms phone-free at night and talking about how feeds are curated. Employers can reduce workplace FOMO by being clear about who needs to be in which meeting and not rewarding constant availability.

Imagine Sofia, 17, who reads her friends’ group chat until 2 a.m. and arrives at school exhausted. Her mother doesn’t confiscate the phone; they agree on a charging spot outside the bedroom and a Sunday walk. After a month Sofia says she sleeps better and the group chat isn’t as dramatic as it looked at midnight.

Whatever your age, the same truth holds: you can’t attend every life. Choosing yours deliberately is the point.

FAQs about FOMO (Fear of Missing Out)

What does FOMO mean in psychology?

FOMO stands for fear of missing out, and in psychology it refers to a pervasive apprehension that others might be having rewarding experiences from which you are absent. It includes a desire to stay continually connected with what others are doing. Researchers measure it with the Fear of Missing Out Scale, a 10-item questionnaire introduced in 2013. It is treated as a feeling and a trait that varies from person to person, not as a disorder. Everyone has moments of it, and it becomes a concern when it is frequent, distressing or hard to control.

Is FOMO a mental illness?

No. FOMO is not listed as a diagnosis in the standard diagnostic manuals, and the popular label “FOMO syndrome” does not describe a recognized disorder. It is a common emotional experience that sits on a spectrum, from fleeting envy to a persistent preoccupation. That said, strong FOMO often accompanies anxiety, depression, social anxiety or problematic smartphone use, and those can be assessed and treated. If your feelings are intense, long-lasting or interfere with daily life, a therapist can help work out what is going on, whatever the label.

Why do I feel like everyone else’s life is better than mine?

Mostly because of social comparison and selective visibility. People tend to evaluate themselves against others, and social media shows highlights, not ordinary days. You compare your full, unedited life with their curated moments. Unmet needs for connection, competence or autonomy can intensify the feeling, as can anxiety, perfectionism and low self-esteem. It helps to remember that everyone has dull evenings and private struggles that never appear online. If the feeling is constant, tracking when it spikes often reveals a few specific triggers you can change.

How do I know if I have FOMO or just normal social curiosity?

Look at the emotional tone and the control you have. Curiosity feels interested and light, and you can put the phone down. FOMO feels anxious, restless or envious, and it pushes you to check again and again. Other signs include saying yes to plans you do not want, feeling worse after scrolling, and struggling to enjoy the present. The research scale is not a diagnostic tool, so a more practical approach is to ask what it costs you in sleep, mood, money and relationships. If the costs are low, it is probably ordinary curiosity.

Can social media cause FOMO?

It can intensify it. Social platforms make other people’s activities constantly visible and reward frequent checking, which feeds comparison. Studies link higher FOMO with heavier and more compulsive social media use, though the relationship probably runs both ways, since people who feel disconnected may turn to social media to feel included. A randomized trial of undergraduates found that limiting use to about 30 minutes per day reduced loneliness and depression, and both groups showed lower FOMO after monitoring their use. The effects are modest, and not everyone is affected equally.

How can I stop feeling FOMO?

You will probably not eliminate it entirely, but you can turn it down. Track your screen time, set a daily limit, and mute accounts that trigger comparison. Write down the thought behind the pang and test it against what you actually know. Practice letting the feeling pass without acting on it, and spend your time on activities that reflect your own values. Building regular, real-life contact with a few people addresses the need for connection that often sits underneath. Give changes at least three weeks, since habits take time to shift.

Is FOMO worse in young people?

Research has concentrated on teenagers and university students, who use social media heavily and are at a stage when belonging matters a great deal, so most data come from them. That does not mean older adults are immune. Remote workers, new parents and people in midlife also report it, and studies of age differences have produced mixed results. Rather than assuming FOMO belongs to a particular generation, it helps to look at the circumstances that trigger it, such as transitions, isolation and heavy exposure to others’ highlights.

Does FOMO ever go away on its own?

Sometimes. For many people it fades as life stabilizes, friendships deepen or they spend less time comparing. The feeling often spikes during transitions such as moving, starting a new job or ending a relationship, and eases as new routines settle. Without any change in habits, though, it can persist or return, especially if it is driven by social media use, perfectionism or anxiety. Small deliberate changes tend to help: limiting feeds, choosing a few meaningful commitments and learning to tolerate not knowing everything. If it lasts for months and weighs on your mood, extra support is worthwhile.
