My mom is 71 . She still independent on the aspect she still drives to the store, Dr's ect. But she has fallen several times in her home . She cant take care of basic needs, laundry, dishes, taking trash out. Cleaning. She's a hoarder and we have tried and tried to get the place clean but it goes right back. She has said she would like to try an assisted living place but they are expensive. She does not want to lose any driving privileges at all. Not sure where to even start!
If she has a house, consider renting it for income to assisted living.
Maybe it is time that you start to limit what things you are doing for her, as I hate to say this, but it sounds like she is being spoiled. Then look around for senior apartments, the rents are geared toward one's income. She would be living with people near her age. She could create some new friendships where they help each other :)
