first of all *hug*
Secondly, i have to tell you that i have never had to deal with anything this severe with my mother...but it sounds to me that you need to first of all

a) take a few days to stay at a friends house or a relatives just to clear your head

b) Get into counseling so you have someone who will listen to your side of the story, getting that frustration out is very important.

I hope all goes well, i know this is a tough situation, and i hope all turns out well. Sorry if i wasnt to much of a help for you, i try.
