A friend of mine has had a caregiver for approximately 1 month who is now trying to make all decisions for my elderly friend and wanting to be at any meeting, asking me to stay away, and seems to be trying to make a case that he is having mental disturbances due to a meeting. (During a very lucid conversation with his lawyer over other things, they asked me to act as his power of attorney. Which I initially declined. But then accepted to help him.) As a couple they were somewhat solitary people, but we had a good friendship for decades. I was willing to help because of that friendship. My concern is this caregiver, who is very good with his physical care, is wanting to be in charge of all of his affairs. After only 1 month she is trying to say that she knows him better. (It is around the clock care however that is split between caregivers, but she is the lead person.) Do I need to be concerned? Should I talk with the supervisor? Am I the one in over my head?
