You need to check on her social security. If she was receiving it, you might be entitled to receive something. And if she was receiving a pension payment, she might have been offered an option that carries over to spouses. Again, you need to look into these. Legal aid might be able to give you some info. At least call them to see if you qualify for their help. And as I said earlier, contact Time Warner to see if you qualify for a reduced rate based on your income.
Maybe you can take in a boarder who will pay rent? Or despite the fact you say you have a disability, perhaps you can receive training through an employment agency--you might be able to earn some type of income. Sometimes employment agencies will offer training.
You will need to find out the cost of property/school taxes and set aside an amount of money monthly to be sure you don't lose the house. Before you lose the house for a lack of money, at least sell it for the money. You don't want to fall behind on your taxes and lose the house altogether.
Again, Legal aid might be helpful for advice. You need to put your photography gear desires on a back burner for now, Bill. There are more important things that need to be addressed first---food, health, and housing--which are the basic staples in life. Please, contact Legal aid to see if they can help.
