I agree with NuckingFutz. You need to call someone who can help you.

Your mother is not supposed to hurt you, she is supposed to love and protect you. But since she is not doing that you have to do it it. That is not fair to you, at all, but there it is.
Her abuse is not about you or anything that you did. It is about her and her issues. She needs help too.
Be strong and keep talking to us, if it helps.

(NF - is your signature line broken? I don't see the phone number you mentioned. Maybe it's just me, I don't know.)
