You can't do it all!! One thing that has helped me when I am overwhelmed is to have a 15 minute day. I actually set the timer and work at something - dishes, laundry - for 15 minutes. Then I read or sew for 15 minutes. That's all I can cope with. You might try 30 minute or even 1 hour days.
Phone calls, too. My friends know I'm in a 15 minute day!!
It helps me keep my sanity.
