I am disabled at seventy, my golden retirement years, what a laugh. Anyway, you have Medicare, Medicaid, these should help you. They both offer a visiting nurse, someone to cook or bring you food, my father had this done, we lived to far away and, he wanted to be independent. The church, we have a very good program at our church for the seniors in your condition, other places like the Eagles, the Elks, the Kinghts of Columbus. You have to let your finger do the walking.
Check with your local county and state health first for emergency needs, go from there.
