I've been there. It does get easier if you keep yourself busy. I find that cleaning, exercising, and doing things with the kids keeps my mind off of things.
Last time I went through the D process I was able to get my mind right by doing yard work with an axe taking down trees and hauling the pieces off to a burn pile.
Keep the faith... goes without saying I'm sure.
