I don’t think that @Matt_was_taken was being mean to you, or meant it to come across that way.
You clearly do have some issues about your past, school, friendships etc, it’s nothing to be ashamed about. It’s probably a good idea to talk to someone.
I was bullied quite badly as a kid, but at senior school I went to the same school as my cousin (who was a bully himself), but protected me. Just so he could bully me himself.
I don’t really have any friends left over from school, nor would I want to. It probably has messed me up socially and anxiety wise. But now I just have a very small set of friends who know what I’m like, and to be quite frank I don’t really care whatever anyone else thinks.
