Ask questions. Ask your doctor and/or your pharmacist to write down or spell the names of the treatments that you will be having, and to explain their effects and side-effects.
Housework
Freeze a big cookup and keep in the freezer for when you have chemotherapy, and are not feeling well. Ignore housecleaning – spend your days doing stuff you enjoy. If the housecleaning is too much employ domestic help, or ask family or friends to assist.
