I know how you feel. Working gave me a reason for getting up and moving. Now I have no reason as DH gets the boy off to school right now. I need structure and right now I don't have it. I keep trying to do "busy work", right now I am knitting my great-niece a hat and working on a baby quilt, but I can only do that so much in a day. My house needs a good cleaning, especially the kitchen, but I just don't feel up to it.
Anyway, no words of encouragement just hugs and understanding.
