If you are disabled, there is only so much you can help with in each day. Give yourself grace for what you miss, and if it happens to make you weaker and sicker, give her the bills. :) No, seriously. (I don't really have the nerve to do that myself, but it happens to cut into their lives in other ways when they don't help me help them ;) .) Try to hire someone to come in and help clean, or make a friend who can help you clean, someone who can show it's not normal for a disabled person to be stuck with EVERYTHING just because there is free rent. Because you will get sicker if you just try to do it all. It happened to me. Guardian makes many good points, but might not know some people will just take advantage and make it worse, and excuse it by saying, "Free rent? Where will you go? You're disabled? Blah blah blah?" Go to counseling and mention it there too. They might know of some agencies like home health care aides or others who can come in and help put it right, show you new ways of doing some of the chores, give you a list of different types of implements to make it go smoother for you. You might even get some of the items free or at a discounted rate. This comes from an elder who is disabled but helps with the chores and has to just say "Oh well, I did this at least" if no one else helps and it's not all done. People will either get the point or they will be annoyed and have to wait for something. God will step in eventually. Pray for your sister and your own heart and health too. EDIT: Someone thumbs downed this, and I bet they don't have serious physical health issues and difficulty keeping employment because of it, and I bet they were never treated like a slave and not even like a sister or daughter or friend.
