How do you survive financially?

I can't afford anything. I have no outstanding debts to anyone, I don't have a car, insurance, medical coverage, school bills, nothing. I only buy the cheapest foods, and the cheapest toiletries. I work as many hours as I can during the week, usually 30 to 40 if I'm lucky. I never buy anything for myself anymore. I can barely afford rent.

How do you guys do it? I need help.
