MS and Family

I have had MS, Lupus, and RA for almost 16 years now. I retired and moved south to get out of the snow and cold. My sister came with me because she was having in our home town. My sister has cirrhosis. She drank hard for 45 years. She expects me to take care of her, help her shower, fix her meals, get her pills, whatever she thinks she needs. I have no one to help me and some days I have horrible thoughts about her and what is expected of me. I barely know what to do anymore. Thanks for listening.
