Parents have been married 71 years and my mother has taken care of my father all these years. Now he is almost blind MD and she is tired. He can’t drive so she does that too. They are getting on each other’s nerves and don’t think the other cares. My father refused to go to the doctor when we told him he was going to give him a memory assessment. My brother and I don’t know how to help them. No financial resources just Medicare and what we give them.
