Yes that was a little hard to read but its poor situation from the sound of it.
If it's as horrid as you say, leave.
It's easier than you think, find a friend who will put you up or couch surf a little, I'm not in the states so I can't offer any advice as to any organisations that could help (im sure someone will point out somewhere) but here calling the right domestic violence place will get you emergency housing, it's not usually all that impressive and it's short term (2-3 months) but gives you time to get some income going and get ya shit together, much better than living at home from the sound of it
