I wish I could jump to the computer screen and give you a real hug. ((((((((((((((HUG)))))))))))))))
I don't know how long you have been struggling with SI. Have you ever considered applying for Social Security? If you have been bad off for a while it may be something considering.

Also if you can't work There are places that will help with most bills (utility, rent, morgage) Some places to try:

Salvation Army (Utilities, Food, Rent or Morgage)
Catholic cherities (Utilities, Medications, Medical Bills, Rent, Morgage, and Food)
Job and Family Services ( Rent, Food, Medical, Cash Assistance,)
United Way( Not sure but worth trying)
Local Churches usually help with food and meals

If you rent sign up for metro housing if you are not already on it. (Wait List where I live)

Both elec. and gas companies have budgets, but try signing up for pipp It makes your bills based on income.

The phone companies have something called lifeline. If you have a medical condition they can't turn off your phone. Your condition qualifies. It will lower your bill low.

Hope this gives you some peace of mind.
