I am stuck in a toxic relationship

I want to leave. I can't. If I do I won't have my daughter cause I don't have a job.. and I can't live without her. I'm jobless so I wouldn't be able to care for her and jobs around here are crap pay and day cares are super expensive.. Edit. There's mental and emotional abuse but no physical. I know it can get to that and I don't want it to. I'm on Medicaid and my daughter is on wic stuff
