I'm not laughing either, and I agree with others that it sounds like some kind of depression for her. But this is affecting you also, and not good!

I live alone, but sometimes I just feel overwhelmed by the work to be done around my house, especially with a full-time job. It can get pretty bad here until I can't stand it anymore! Yesterday, on another forum, a woman told me of a website called www.flylady.com. I looked at it, and found it to be a site for organizing your home, as well as feeling good about yourself. Perhaps you and your wife could look at it, in a friendly way for her to get motivation...or she may not want to do this. Just a suggestion.

For me, clutter, dirty laundry piling up, dust balls, dirt, etc., are directly proportional to my mood and self-image. When I get the place clean and tidy, I feel better, loving my surroundings and like being here! I hope your wife can find the motivation to do this.
