My parents are near 90 years old and live in their home. My sister, who is unmarried, has moved in with them. My sister does the majority of the caregiving, partly because she is living with them and partly because she is extremely meticulous about it and my caregiving does not live up to her standards. All I ever wanted growing up was for my dad to treat my mom the way she deserved to be treated but that was asking too much. As a result, I've never been close to my dad. My sister had a tumultuous relationship with him also and eventually told him he was ruining her life. A few months later he had a serious accident and now requires daily care. Since the accident, my sister's number one priority has been his total and absolute happiness. I think she feels guilty because she had told him he was ruining her life. My mom is the most wonderful person in the world. Even though she is still living in her home, she has lost her independence, must essentially live under my sister's rule, and I feel she has lost her will to live. Her appetite is not very good and tests show she may have had a heart attack sometime in the last year. My mom would be much happier if my dad was in a nursing home but my sister will never ever let that happen and she's in charge. I cannot bear the thought of my mother living like this because it's her home, not my sister's. I try to make my mom's life better by getting her out so she can have fun but all she wants is to have her life back. It's just so awful and it's been this way for so long and I've stressed and cried and prayed and racked my brain over this for so long -- I just don't know what to do. I really feel like there is no answer but I cannot let my mom just waste away. She tries to put on a brave face but I know how I would feel if my son moved in with me in my old age and took over my home. Is there anything I can do? My sister is in charge and crossing her is really not pleasant.
