I have a different take on it since I was the one to apologize.

I was bullied all the way through school for my appearance (I used to be on the chubby side, not anymore) and because I was gay. It was a constant thing and I was really scared and therefore I developed a very hostile personality in order to guard myself from others, which led me to become a bully myself. I would talk down and say mean things I knew would hurt, sometimes to defend myself, some other times I would just target people I would perceive as "weak" and go off on them whenever I had the chance. That went on for a while but at around the age of 14-15 I started to realize how wrong and terrible my actions were and I just felt really really bad, because all I was doing was perpetuating the abuse I was experiencing myself, the bullied bully that's so fucking stupid. I then personally reached out to some of these people and apologized because I genuinely felt like steaming shit for it and for the way I made them feel. To my surprise they were quite receptive.

Looking back I do feel bad and ashamed because of how chaotic of a situation it was, me being abused and coping by taking it out on people, but I guess I just didn't know any better. No one ever apologized to me and I don't really expect it to happen, mostly because I have very very little contact with people from school and I simply just don't want it.

I'm 21 now, I've changed a lot since then and I've learnt and grown from my actions. I do think that apologizing was the right thing to do but I also think that not behaving like that would have been even better.
