I can relate. I turn 22 in a couple months and I feel like I've squandered my time as a young adult because I keep jumping college careers searching for a path in life, but never finding anything that ignites any passion or self-identity.
I know I'm still young, but it depresses me to see my friends and siblings commit to a career early on and get degrees/real world experience, while all I really have to show for myself is nearly 4 years in fast food.
I keep thinking about it daily and it sucks all my self-confidence, which reflects in my poor performance towards taking risks or going on dates.
But in the end, I realize its the mindset that destroys me, which I hope you don't adopt OP. I've never been bullied and nobody ever tried to put me down, so its sadly humorous how I made myself my worst enemy.
