Bad diet

This pregnancy my husband has been really strict with the money and only bringing home fast food. I’m in a super controlling relationship. I need to leave. But I’ll have no where to go. Majority of food I have been eating is fast casual or chick fil a, McDonald’s. I don’t have a choice. I’m scared that my baby is going to come out with something wrong. I applied for food stamps. I’m very frustrated. My first pregnancy was all organic because I was working. He insisted I stay at home with our toddler and this is how I’ve been living. I really don’t want to harm or mess up my unborn child.
