Mom lives by herself and all her kids live many hundreds of miles away. She is losing her ability to deal with her finances. (She thinks she has no money, but has a lot! She withdrew a large sum from the bank after Dad's death and has been living on that cash for 4 years. She has difficulty writing checks and withdrawing money from the bank now.) We tell her what to do over the phone, but she never does it. I sent her power of attorney papers to get signed and notarized, but she doesn't even do that. She refuses to move anywhere near any of us kids, and we cannot move there. She has almost completely isolated herself in her home. Her only friend in town is probably gong to die soon and then she'll have no one. I tried to get her to look at some assisted-living facilities and she about tore my head off. She's in pretty good physical health, but her mind is obviously going, but she doesn't seem to think so and gets upset if any one of us tries to do anything about it. Should we do something drastic like legally wresting control of her life from her?
