Pregnant and neglected/abused

I been with my boyfriend for 5 years, we were evicted 2 years ago from our apartment so we live with his parents. Which are emotionally draining and my health problem has developed because of them. I have been dealing with heart issues and anxiety because his parents. I suffer from stress I had from the past cause my father was abusive. And loud noises trigger stress in me. That's not the only thing I'm dealing with my boyfriend told me he's falling into addiction. I feel trapped and don't know where to go. He hasn't maintain a job or steady income. I want the best for my child and me. I had to start working again to maintain my self at least. Work is getting physically hard for me. I want to move. I have no family that can take me. Everyone lives with roommates. I desperately want to find my own place. I live in MA. I don't want to go to a shelter either!
