Idk what to do

So I'm going through a pretty rough time right now. Im 20 years old and I have a 5 month old baby girl and I'm planning on leaving my abusive boyfriend/baby daddy. Sadly he is the one with a car, a job and money. When I leave him I won't have anything. I know I can stay at my grandmothers but I have no job, no money, no car and no one to baby sit my daughter (my grandmother is 82) even if I got a job. I'm very lost and emotional right now because I don't know what to do. Any advice would be great :(
