My mom resents me for wanting to move out and initiates fights that I'm too stupid to stay out of. How do I keep the peace until I get on my feet?

I had a really lousy year and had to move back with my mom who is in a nasty divorce with her pig husband. I'm not working but I'm taking a full-time load online and contributing with unemployment and food stamps while looking for jobs and keeping up with school. We are in a new town and a new state and I absolutely hate it here since there are no prospects and barely any sidewalks. I think she has a borderline personality and is either jumping on every word I say ( I swear she treats everything I say like it has a double meaning.) or looking to me for strength. Whenever I give her my input, she accuses me of trying to be the mother and run her life for my own benefit. Honestly, I just want to get on my own feet, pay her what I owe, and move on! I have trouble concentrating on school, lately, because of all the fights we have. She brings out the worst in me and I hate it! I don't know how much more I can take. I'm broke and I owe her for covering the cost of my dental implants since they are not covered by insurance and I couldn't afford my rent since my hours were cut and some other really unfortunate things that happened. I love my mother and I want to do right by her, but I just can't take this fighting anymore. She's up, she's down! She blames me for decisions she can't make for herself. She says these hurtful things and accuses me of all this stuff and gets me angry and then backs down and plays the victim. I don't want this kind of relationship with her, I really don't what do I do?
