Her doctor has diagnosed with her dementia; she has no short term memory. Her house in Florida was flooded and is uninhabitable. My brother and I live in SC and we took her in in July to take care of her. We take turns, but it is taking a toll on our own family. She has stopped making mortgage payments. She refuses to talk with us about the house and turns mean and yells at us that everything is all right and is paid off, then 15 minutes later she says she's sorry and that I need to stay out of it; everything has been paid off. She tears up important documents my brother mails to us for her ( her mail is going to his house). She has high blood pressure and is on medication; there are many days she will not take a shower or bath unless we make her. I am afraid to take her to her house in Florida as she refused to leave the last time we were there (in July when the house was flooded). When we went to the VA, the police asked my husband to take her home because she refused to listen to anyone. We are at our wits end. Please help.
