She lives in her home, says it is not her home. Hasn’t driven in five years. Says she drove yesterday. Wants her car here and her grandson is using it. He asked to borrow it and she agreed. Then says she didn’t agree. Gets very angry and agitated can no longer drive as she failed the eye exam. This used to be a thing once a day, now several times a day. Says I don’t care about her or I would help her. I am primary caregiver for the last 2 1/2 years. Tried driving her around awhile and then back to house. Didn’t work. Suggestions?
