People who intentionally cause others pain aren't even worth the pain that they cause. And they're certainly not worth taking your life over.
Just please don't do it. Somehow, someway, things will get better. I know it seems like they never will, but it's your life and if you try and refuse to let people like that break you down, everything will get better.
I know you don't know me but you can email me if you need someone to talk to. gimmecoffeenskittles@hotmail.com
