Thanks for all your responses, and I've now got a few ideas. First of all, I'm going to take everything in small steps.
The first thing I need to get a handle on are my hands, which are dry and cracked from constant washing. Stopping washing is obviously part of it, but I plan to get some cotton gloves I can wear overnight with lotion - I've had them before and they work wonders.
I also hope to start NaNoWriMo tomorrow, and I've decided that I won't let myself go on the internet until after I've written something.
Then, I'll do vaccuuming, because that's the least stress-inducing cleaning.
Again, thanks, everybody.
