People that were not “liked” or “uncool” in High school where are you now?

I’m not particularly popular in school and I used to think I was fine with whatever people said about me but when random people that I have never even talked to start being mean to me it does bother me. And honestly I have let that get to me too much recently so hence the question because honestly I just want to feel like everything will turn out just fine despite all the shitty things
