Another possibility is to work from home in a freelance capacity. Industries like mine, the language translation field, are over 80% freelance, so there are few "rat race" jobs even if you want one. Take a look at books about home-based businesses for ideas.
I don't work much, and don't make much, but can cover my expenses and continue to live on my own (which is my only option at present).
Also, consider moving to an inexpensive part of whatever country you live in. If you're in the U.S., check out websites like city-data.com for all the details about cost of living, lifestyle, amenities, etc.
