Here are a few suggestions: Get a high stool for the kitchen. That way you don't have to stand while you are washing dishes and doing the cooking. Use disposable dishes whenever you can and throw out instead of wash! Get a lightweight vaccuum and when all else fails, lower your expectations.
Oh my lord!!! Can I relate to this problem!!! I have a very difficult time with trying to do housework. Previously, I lived in a three story townhouse, and just going up and down the stairs was awful for my bad knees. I moved into a much smaller apartment last fall, so everything would be on the same floor, and I'd have much less space that needs cleaning. Unfortunately, I basically got moved in just enough to live, but still have tons of boxes that haven't been unpacked yet!!!
I have a horrible time trying to do housework, but since nobody ever comes to my apartment except my dad, everything just piles up. My mom always says that she needs to come over once a week and help me clean up, but she's been saying that for six years!!! She did come over last Saturday to help do some dishes, but the first half hour she was here, all she did was fuss at me about my living conditions, which I totally didn't need. I feel bad enough about the place being a mess, but the pain that comes with trying to clean up is almost unbearable. It also doesn't help that I have three cats that shed all over the place, and love to knock thing over all the time. Heck, my folks could afford to have someone come every couple of weeks and keep the place in good shape. I'm just tired of all the lip service and all the pain that keeps me in this mess.
