I want to kill my mother

She calls me a bitch, punishes me unfairly, and even says that she wants my dad to rpe me bc my dad has a rpe and incst f3tish. She just drains all the fun and happiness from my life I swear I'm just so tired of even hearing her voice I want to murder her when she speaks. I have dreams and thoughts about it frequently. Srs I don't know what to do.
