If you are not currently working, volunteer and
do something you have always wanted to do, but you couldn't do because of marital obligations. My do something is learning how to become a photographer.
Find a way to take care of yourself. If you don't eat, eat, skeletal is not sexy. If you do eat decide if it is worth it. Find something that can occupy your mind and your time. Exercise, get up and walk, feel the sunshine on you face. Make yourself. Trust me, I know there are times when it is impossible. Try. Just Try. You will find your bad ass self so much faster.
