Hi, jojo...welcome back!
Arrrrgggghhh, I can totally relate. I have a black & white personality - I want everything perfect or just won't deal with it at all. And since I haven't dealt with the house stuff for awhile it's all piled up. I thought I would win "most cluttered house" award but sounds like it comes along with the depression.
I like your idea Kimmy. Keeps the cleaning/clearing confined to a manageable area. I tend to start with one thing, then go into another room to get something, see something there that needs to be attended to, and never finish the first thing.
I like the flylady site as well. A kind of variation of her 5 minutes is when I'm watching TV, I see how much I can do during the commercials. Generally it's either loading or unloading the dishwasher.
Good luck!!
