It was very good of you to try.I looked after both of my grandmothers for awhile. Dad's mom was fine. Mother's mom was horrible. Within a couple months, I made my mom come home to take care of her own danged mother. My dad was working in California, so she was there with him. I had 3 young kids of my own to care for at the time, and didn't really need her mother's nonsense. She kept throwing herself on the floor, trying to hurt herself bad enough to be hospitalized. The main floors were carpeted, and I had thick padding under the carpets. She couldn't really hurt herself much, but it didn't stop her from trying. My grandfather, her husband, fell and broke his hip. He was in the hospital for a hip replacement, followed by physical therapy to regain the ability to walk. She was worried that he was going to cheat on her with a nurse, and she was jealous because he was getting so much attention from the doctors, and nurses, and she wasn't. She had difficulty walking, because she had suffered a stroke a couple years earlier. She had to use a walker, and even with the walker, needed a bit of help getting around.
I had to get a hospital bed with side rails, because she would roll herself off the bed, and onto the floor, as I said, the floors had thick padding, and carpeting, so she really couldn't hurt herself, but she weighed about 280 pounds. When trying to pick her up off the floor, she would go totally limp. It took 2 - 3 strong men to lift her dead weight up off the floor. I had no alternative but to call in the paramedics to help lift her. She constantly complained she had to go to the bathroom. At first, I'd help her get to the bathroom, get her on the pot, and tell her to call me when she was done. Remember, I had 3 young children to take care of too. She wouldn't call me. She would try to stand up, then throw herself on the floor, because the bathroom was not carpeted. One of the times she did this, she hit her head hard on the bathtub. Her eyes rolled up in her head. I thought she was dead. Scared the heck out of me. I called the paramedics. She had only knocked herself out, but had a big gash where her head hit. They took her to the emergency room, and she got stitches. After that, I learned I had to stand there, and wait for her. She really didn't need to go to begin with, she just wanted to hurt herself, so she'd wait, and wait, and wait. She knew sooner, or later, I'd have to go tend to my kids. We tried the portable potty thing, by her bed. She refused to use it. Finally, I had her doctor order a catheter. and got some adult diapers for her. When she'd cry to go to the bathroom every 3 minutes, I told her to stay in her chair, and she could go right there. This behavior continued, and after 2 months, I threw in the towel. Around that time, it was time for my grandfather to come home, but he needed care too.
That's when I told my mother it was her, and her sister's job to care for her parents. I refused. She was asking too much of me. I had my own family to care for, and it was not fair to them either. Of course, it was out of the question to expect her sister to help. I threatened to sign them into an elderly care facility, if she didn't come home to care for them. She did come home, and took care of them until my grandfather was good enough to go home, and take care of her, and himself. We did have someone come in 3 times a week to help with the housekeeping, and cooking. They had a lawn service, so there was no yard work. They did fine, until she died, then my grandfather moved in with my parents. He lived with them for years.
Sounds like the stroke messed her up mentally...of maybe she was always a bit of a crank?
