sorry I posted some suggestions but then looked at your other posts. I think you should call a taxi And go to a shelter and inform them that you are inSDDI and have no place to live, boyfriend's house is unsuitable.

They'll help with subsidized housing/group home.

Call animal shelter and explain Situation, let them take your cats. When you get subsidized housing, get your cats back. Your cats are unsafe in your house. If you have fleas, so do they. It's unsuitable for animals. They stuck and have no choice.

When your car is ready then shelter can help you to get it. Do it all tonight. Look up local shelter. Call taxi. There is light at the end of the tunnel. Actually while you are calling taxi, call your doctor. Tell them what's going on. Things could be better for you, starting right now. Do it. Hugs.
