My mother is 82 and is declining. We just saw her doctor on 4/25. I also have a 60 year old sister who is developmentally disabled and I help my mom and sister by taking them to the bank, grocery store, hair cuts and medical appointments. My mother and my stepdad (died almost 3 years ago) and that's when I stepped up. I have two other siblings that do nothing or even a phone call. My sister had been able to hold down a job and has savings in the six figures and my mother has an estate worth in the six figures. My mother nor my sister have ever given me money. And I have been driving them around for 3 years. I don't work because I'm disabled (I'm in the process of applying for disability) and I spend what savings my husband and I have. I am resentful because we're using our future retirement money on my mom and sister. What can and should I do. Any answer would be helpful. Thank you.
