I apologized to a guy I bullied. Was it the right thing?

Hi. When I was in middle school, there was a guy that my friends and I picked on. I know I'm a horrible person. And YES. I have been bullied. I bullied him because of my own insecurities, my own self hatred. I guess to feel better because people bullied me... Even though his friends and him called me a slut and whore in high school, I let that anger stay in and basically stopped talking to him.

It's been about 5-6 years since I saw him. I do not live in the same town anymore. I never kept contact. We were friends. Like all my friends were close and like...in a clique. But we picked on him and well, we all picked on each other but his was worse..

I sent him a message on facebook since that's the only way to contact him. I apologized and told him he didn't need to forgive me. That he's allowed to be angry, to cuss me out, to wish bad things upon me. Part of me feels like it's a bad idea to have sent the message now. I can't take it back.

I know. I'm a very horrible person. I hate myself for how I was when I was younger.
