My mom is emotionally/mentally abusive?

I had a mother who sounds very similar to yours. i left home when I was 16, and although the first few years were hard to get on my feet, they were easier than putting up with her and the mental and physical abuse. Leave. Just leave. Can you go to your Dad's? Have you got friend's you can go to? I know it's a big step, but it sounds like it's time. Good luck.
