It doesn't sound like you're ready for a nursing home yet. When you are and a doctor will confirm it, you can apply for medicaid as long as you don't have more than $2,500 to your name.
Please don't worry about this process, we just went through it for my mom and the medicaid people were wonderful. Once her funds were paid down, the nursing home gets her retirement and social security checks and medicaid pays the rest. I know the government negotiates the monthly amount and pays about half what we pay privately (which was $8,700 per month), but nothing in terms of her care, room, etc., changes.
Good luck and God bless!
