Get out of that place...just go. If you really want to be away from all that evil that is there. Pack up whatever you can carry and get out.
There are shelters, go to a church and tell them you need sanctuary from these people.
The longer you stay the more danger you are putting yourself in. Go to someone that will help...go to a church, salvation army - a soup kitchen or even the welfare office. If you are disabled and get disability or SSI then go to them and ask for references that can help you. Go to the housing dept and tell them you need help.
Go to a women's crisis center...look it up on line or open a phone book.
Do not be an ostrich and stick your head in the sand! And if there are kids involved - go to welfare and ask for services! You being disabled are able to get protection from someone that's abusive - be it physical or mental. If there are kids - depending on how old they are...they could use some intervention too.
This situation is dangerous - get out now. What were you doing homeless on New Year's eve...you should have gone straight to a women's shelter or salvation army. There are groups that help women that are in need, especially those that are disabled. Plus those kids are in the middle of this? If you've cared for them, how do you feel about leaving them in this mess? At least see if someone can check on them after you are out of there and maybe they can be moved to their mother's place or to a relative's home.
Don't be afraid - be strong and get your rear out of there. There are plenty of bad people that will manipulate you and take the control of your life from you - don't let them do it! It's your life...you decide what to do and you choose how to live it. Never let someone take that away from you...never!
You pack up your things, you wait till the opportunity is available. Everyone's asleep, or busy or off doing something and you have a chance to slip away. Go out a window if you have to...and can - or at least get your stuff out of it. Then find a way to go outside, get your stuff and get out of there as fast as you can. Don't weigh yourself down either. Clothes you can get more of, take only the barest things that you need. Bottle of water, some crackers or such - flashlight, map if available, your personal items, money, ID and such. Shouldn't be much more than can fit in a backpack.
Things can be replaced - your life can't be.
Good luck and be strong....
