"Bullying", in my case, at least, was a constant barrage of insults and public humiliation at my expense. Every day, multiple people poking fun at my appearance and weight, and making a school-wide ordeal.
Look, it sounds like you had a rough time in school for a while. However, I don't know anybody else's side of the story. You were an asshole in HS, so you probably are exaggerating. I don't believe you and if it happened, you probably had it coming.
