OK..yard can wait...till spring generally...does teenage son do much yard and garden work? If not, yoke him up. Filing can wait. CLothes can be put in baskets and just pick out the ones you need. Dishes are important. Spring and fall cleaning can be done next spring and fall. If you have friends who can help with billing, stuffing the envelopes or whatever, ask if they can come over for a bit and help. One will probably compulsively start wiping down counters or folding clothes..let her...

Son can certainly clean the bathroom, vacuum, keep up on dishes, especially since he probably has some holiday time. Between Christmas and New Years is a good time to declutter...with a friend or sister or someone to help make quick decisions. Travel light and take no prisoners...get rid of everything that does not serve a purpose or make you happy or is a family heirloom of modest size.

I personally would try to go into work to do the billing and catch up there, rather than in a house where I saw clutter and projects. I would cancel all pre-Christmas events that were non-essential and tell people I would see them around New Year's.

Call for help..if I were nearby I would come over and wash dishes or input stuff into the computer..people want to help...
