First, by law ERs have to treat you whether you can pay or not.
Second, cut back on (wait for it....) your expenditures. Sell that second car. Take public transportation. Even here in the 3rd world, we have busses that go just about everywhere. That'll save on the price of gas, liability insurance, and preventive maintenance.
Third, Internet, cable, and cell phone go bye-bye. Basic prepaid phone, and use the computers at the library (big building, lots of books).
Fourth, second job. Even part time.
Finally, you can grow food in a small space. Websites can show you how. Wait- that's self-reliance. Never mind.
