Hello bdgirl: I see this is your first post here on PC. So... welcome to Psych Central.
I'm sorry you are living under such abusive conditions.
No one deserves to be treated the way it sounds like you're being treated. I don't know as I have any good advice to offer you. You mentioned possibly talking to the counselor at school. And that sounds like it might be a good place to start if-&-when you feel you can. In the meantime, hopefully, coming here to PC can be of some comfort & support.
My best wishes to you.
