Start small, like others have said. I am BP, so most in my life is black and white. For me, when depression hits, I used to have to clean the whole house or nothing. It was hard to get motivated for THAT task!!

It took some getting used to, but now I do a little at a time. It keeps me happier and more sane. It also makes me feel good that my kids live in a cleaner, more organized home. It will never be perfect (2 boys, 3 dogs, and a 47yo kid), but trying by doing small things, really, REALLY makes you feel better. It may be hard at first, but make yourself do it. Use your kids as your motivation. It gets easier, because you will see if makes you feel better
