FOMO, or Fear of Missing Out, is a psychological phenomenon where individuals experience anxiety over the possibility of missing enjoyable experiences that others are having. This feeling is often amplified by social media, where people frequently share highlights of their lives, leading others to feel inadequate or excluded. People with FOMO may constantly check their phones or social media accounts to stay updated on events and activities. This anxiety can lead to stress and dissatisfaction, as individuals may prioritize social engagements over personal well-being, fearing they will miss out on something important or fun.
