i had fomo recently. what is fomo? fomo is the fear of missing out. it's probably not an unfamiliar feeling to you as i assume most people feel fomo at least once in their life. the more expanded definition of fomo is anxiety that an exciting or interesting event may currently be happening elsewhere, often aroused by posts seen on social media. i thought that i was done experiencing fomo. i thought i grew out of fomo. i thought i had evolved past the point of experiencing that feeling, but i was wrong.
