My husband and I are very active 69 year olds but my mother is literally draining me emotionally. She has two daughters. I am the oldest by one year. My mother has been hateful to me my whole life but is just the opposite with my sister and her kids. I have taken care of my mother her whole life , especially for the last ten years since my dad died. My sister hasn't lifted her little finger to help because she lives seven hours away. We have tried to put mother in an assisted living but she won't have it. I finally have a registered nurse with her at her home. No matter what I do for her, she doesn't appreciate it. She always gives praises for my sister whom she only sees every couple of years and that visit is just for a day. She does have mild dementia now but I can't tell any diffrence in her actions towards me as they have always been hateful. She still thanks my sister hung the moon. She drives the nurse crazy too. She is mad at me right now and I have to go through the nurse to talk to her. She thanks my 36 year old daughter , who lives two states away stole a pair of high heels from her. I pay all her bills for her and have put five thousand miles on my car taking her to diffrence doctor appointments but when I mention what all I do for her. Her answer is "Who asked you to." I lay awake at night worries about her. I know I shouldn't, but I do. How can she be so hateful to me and so nice to my sister who never has done anything for her?
