What do I do?

My mother’s husband has made it a point that I am not welcome in their home. After a bad breakup, I moved my dog, cat, and myself into my mother’s home. Since then, I am not permitted to eat there, shower, do laundry, etc. So I moved into my current bf’s apartment, and have been working to be as little of a hindrance to them as possible. The only problem is that I can’t move my pets to my boyfriends apartment. He’s allergic to cats and he has already reached the pet limit with his dog. I go to college full time and have a huge amount of debt due to my ex, so I can’t afford a place of my own and have no body who’d be willing to take in my animals for a long while. I’m not giving them away. What do I do? I am trying so hard to get away from them, I’m even selling my stuff left and right. I just can’t stand the insults about how I don’t care about them when I can’t even live there.
