My mother, a former model and television singer, has been emotionally abusive to me since I was born. So disconnected from me is she that she didn't know she was pregnant for 6 months. She's an utterly horrible person masquerading as a nice one, but during her life, she refused to let her second husband see his grandchildren; she used to show up at my place of business to berate me in front of my colleagues; and we just discovered that she has a shopping addiction, so all of the money that my partner and I have given her over the years to help pay some of her bills has gone to her addiction. In December, she fell and broke her ankle and fractured her other foot. She was in hospital for 2 weeks, had 2 surgeries, was in rehab near my house for a month, and is now home with a 24/7 caregiver who she cannot afford. She is confused and agitated, refusing to do the PT that has been prescribed for her, and is obsessing about the "wrong" shoes that I bought her that won't fit over her air cast. She has told everyone --- a visiting nurse, a visiting PT, caregivers, etc --- that I agitate her. I see her once a week because it is all I can tolerate; I'm having heart problems from the stress of dealing with her, her money issues, her insurance problems, her lies, and her abuse. (She has very little money.) But I was raised to believe that we have a moral obligation to care for our senior parents, and so, I do. I have no siblings so there's no one else to help.
I've considered a guardianship, but it's too extreme a measure, I think. Still, I don't know what to do. Thank you.
