I have three siblings, none of whom help with my mother who has end stage MS. Anyone know how to tactfully stop my older sister, who lives two houses down, works part time, and has a five year old child, from constantly expecting me and my elderly father to do things for her, when she does absolutely nothing to help at all with mom. This involves a lot of babysitting which, on top of doing all the housework, shopping, etc., is just too much. I have no time whatsoever for myself. She cannot be left alone and I get so angry I don't know how to handle it. I love my nephew but I can't do it all, I feel because I retired to care for my mother full time that my sister considers me as living in the lap of luxury when it is the opposite. I am exhausted all the time and very depressed. Any advice? She has by the way come out and told me that I "live here rent free" and so I should be doing everything. I buy all my own food etc., i do sleep here, but it is backbreaking work every day and I am getting angrier and more depressed the more she treats me like I am at her disposal because of my "life of leisure." Help?
