Fear of Missing Out, often abbreviated as FOMO, is a psychological phenomenon where individuals feel anxious about missing experiences or opportunities that others are enjoying. This feeling is commonly triggered by social media, where people see friends or acquaintances participating in events, traveling, or having fun, leading to a sense of exclusion. FOMO can impact mental health, causing feelings of inadequacy, loneliness, and dissatisfaction. It often drives people to overcommit to social activities or constantly check their devices for updates, as they seek reassurance that they are not missing out on important moments or connections.
