Hey guys, not really mgtow related but I am curious to know if anybody here was a victim of childhood bullying?

I was constant bullied in school but due to the environment I was brought up (buddhist household that focus on forgiving, peace etc. sort of crap), I never learn to retaliate.

Now I am 27, but there are still rage and bitterness in me. Sometimes I will snap at people who treats me well, and purposely say things to hurt them (like insulting my ex-gfs because it feels good to me).

Its a very dark and twisted place to be in, and I hope to walk out of it and be a better person. Any advice?
