Need own place but can’t afford

Any advice on what I can do. I have 2 jobs, one daughter and 11 weeks pregnant. I live at home with my mom, step dad, and brother but it’s just not working out. Space is too small, and a lot of bad habits over here. Only problem is where I live even one bedroom apartments are almost $1,000 and with me and 2 kids I’m going to need a 2 bedroom and I can not afford that alone. I live in Chicago, anyone know of anything that could help me?
