Well um I'm kinda struggling with attachment issue

I honestly don't even know why did I post it here

Hello, I'm actually not very sure if IT WAS ACTUALLY what it's really called but yea. Asking it here cuz I wanna see how y'all handle it so I can improve mine? (to sum that got the same issue too)

I realized that it was all started when I was 10 (friendship issue). Yea it's still here until now it sucks tbh. I thought that I already moved on and became the better version of myself but I guess I don't. I thought that I don't care anymore about those things like "oh okay fine people come and go it's not surprising" BUT DAMN IT HURTS. I tried man.
