FOMO stands for "Fear of Missing Out." It is the anxious feeling or apprehension that one is missing out on rewarding experiences, events, or social interactions that others are having. FOMO often leads to a compulsive desire to stay continually connected with what others are doing, especially through social media. It involves the fear that deciding not to participate in something is the wrong choice and can result in feelings of regret, loneliness, or social inferiority. FOMO has been linked to negative emotions, stress, and reduced well-being due to this pervasive apprehension of missing out.
