My 82 year old mother just moved in with me after a bad fall. She broke both bones in her lower leg and after surgery had to go to rehab. She lived with my brother in her home, but after 5 falls resulting in breaking bones in 2 years, it was decided she would be safer with me. She is very resentful at not being able to go home with my brother and is very combative with me about everything. Now 3 weeks in, I am just tired. She doesn't sleep well at night and wants to get up every couple of hours. I had to put a guard on the bed to ensure she doesn't get up on her own but I'm not getting any sleep and am feeling resentful that she sleeps most of the day. I can't sleep then because she will get up, or try to whenever she sees I'm not right there. Honestly I don't know what to do about it. She's very mean to me all the time and when I call her on it she says fine I'll go live with your brother. Her safety won't allow that and she doesn't get it. Any suggestions would be appreciated?
