This is my last resort

I'm disabled 33 yr old mother of 4 kids I'm solely responsible for. I pick up any extra work to supplement the 800 dollars a month I get but without a car it's hard because I live ten miles away from anything. I'm going through a divorce and I am so far behind, I worry that my only option for my kids to have a chance is to find them somewhere better. I don't know what to do at this point if I can't get reliable transportation, or pay my electricity. I know I can't make it without them, but if I can't get a real job because I can't get a way to work then I can't drag them down with me. I don't know how to ask for help but I'm out of options.
