Hey Autiger,
I'm sorry for your situation. I really can't offer you any solid advice about what to do when looking for emergency accomodation because I live in the UK and I'm not sure on the methods they use in America. I know it seems like you are being treated unfairly at the moment. It's truly soul crushing being chucked out of the house by people you assume love you. The thing is they probably do love you and see this as their tough love move. I got chucked out too at the beginning of this year because I relapsed. By far the best thing that ever happened to me. I left, went to rehab and got sorted out far quicker than I would have done if I had somewhere to live.
I wish I could say something that would cheer you up but the only thing I can do is offer you my experience of this type of situation. I just hope you try and enjoy the rest of the festive season. You have to go through pain to truly appreciate joy.
Natom.
