My mom is in her 70's and has always had a very dependent personality. Recently she is in a wheelchair and the care has fallen to me. It seems like I have always been the one to do all of the caregiving in my family, even when I lived several hours away and my other sibling lived just 20 minutes away, I was the one who came down and took care of my parents when they needed it. Now that mom is alone, she expects the same thing but to be honest I have had enough of it. She does not appreciate it and lately makes snide comments about even more things I should be doing for her. I have a demanding job, a life of my own, and I am exhausted. I know this shouldn't matter, but my sibling does nothing for her and did nothing for dad, yet is the favoried one and has a copy of her will which she denies me. It is not that I'm looking for something monetarily, I just feel really used. She has set up a situation where I have to 'earn' her love, yet my sibling just has to exist and that's enough. I hate how this feels. How do I tell her that I'm not willing to take care of her like this?
