Be the change you want to see.

I'm sorry you were so horrifically abused. That's awful.

From where I sit, you've nothing to apologize for or feel guilt for. The walking shitstains who tortured you like this do. And so do the teachers who turned a willfully blind eye to all of that.

Bullied myself my entire childhood at home and at school. And possessing zero tolerance for bullying when I see it happen.

I'm sorry you put blame on yourself for being human and pushed beyond the breaking point.
