FOMO, or "Fear of Missing Out," is a psychological phenomenon where individuals feel anxious about missing experiences or events that others are enjoying. This feeling is often amplified by social media, where people see friends or influencers sharing their activities, leading to a sense of inadequacy or exclusion. FOMO can impact decision-making and mental health, causing people to prioritize social engagements over personal well-being. It is commonly associated with younger generations, particularly Millennials and Gen Z, who are more connected through platforms like Instagram and Facebook.
