Need help please

not sure where to post this, I’m 27 years old and living in Florida. I have an 18 month old son and currently six months pregnant. Ever since I found out I was pregnant again my husband has become extremely abusive. This morning it got to the point that I knew I had to leave. I’ve been in contact with lawyers, therapists, and women’s shelters. Unfortunately, I don’t have any place that I am able to run to that is affordable. Does anyone know of any location or programs that help single moms in my situation? I have tried applying for a few but they say I make too much money, although I’m not sure how since I am barely able to put food on the table on my own. I just want to do what’s best for my kids.
