Most social media is fake, one way or another. It is designed to make you feel like you're "missing out". Advertisers want you to feel like you're "missing out" on their services to get you to spend money on them. Influencers want you to feel like you're "missing out" on the same experience as them, cos that gets you to use their sponsors, thus benefitting them. And the general public wants you to think they're always having the time of their lives, cos it looks good, looks popular, people envy it. Every video is the perfect moment, every picture is the best pose, the best light, etc.
Don't let social media set the standard for what constitutes a "full life". Not all experiences are for everyone, and it's pretty difficult to do EVERYTHING there is to do. Sometimes we miss out on things, and that's ok. Socializing isn't a contest. A social life that has one doing more, but not enjoying it, is not "better", imo.
