The sitting around and wondering about x is a mood/motivation killer.
I don't have a ton of advice, because my situation is up and down. I do know that the people I have surrounded myself with are awesome and they are helping. Get out of the house. A simple walk may be the greatest thing you need. Each day is a new one to tackle the things you haven't wanted to. We are all learning how to deal with this some are better at it. I'm praying for you and I know that you'll get better. You're awesome remember that. (sorry I don't have a ton of wise things to say)
