I second the roommate idea, but be very careful with who you choose. Some roommates can turn out to be bad news in terms of not helping out with chores, not paying their half of the rent, etc.

Also I see that you mentioned you don't work, but are you able to get a part-time job? I am on disability but work very part-time as well (only 15 hours a week) and this small amount is doable for me and provides a bit of extra income. Just a thought, if you are able to do so.
