I take care of my mother who is blind with a lot of medical issues, I try to get her to go to a medical day care but she refuses. Any advice?

Stating she can’t see and they might let her fall. She don’t try to do nothing for herself. I told her several times that she can run her water and get in the tub and bath herself without waiting for me to do it. She don’t even want to dry herself off when she gets out of the tub and lotion herself down.. she wants me to do it. She is so negative all the time, talks about me to my two sisters who don’t do nothing for her and never did. They are both nurses. One moved to Florida and the other one lives about 20 minutes away. I am the one stuck with her. I have a 14 yr old daughter I adopted that has a weight issue I am trying to deal with and get her healthy. I went through breast cancer last year and I am still trying to get myself together after that without any help from my siblings. I am tired of taking care of my mother and need a break. I don’t want to put her in a nursing home because she worked in one a majority of her life and these nursing home are horrible. She tells my sister’s she would go to one but tells me she don’t want to go to one because she can’t see and she has a difficult time walking. My sister’s only think of themselves and their families. My mom is always them and I am tired of it. I am emotionally and physically drained. Sister’s always traveling and enjoying their lives while my daughter and I are stuck here with my mom or dragging her negative behind with us. Always complaining and talking about the same thing over and over. I know I am all over the place, just venting. I have been helping my mom all of my life, she raised us as a single parent.
