I thought I would be a wallower in this sitch. That fits my highly emotional personality. But instead I found that I didn't want to wallow. Yes, I was sad and angry and upset at lot. What helped me a lot was to ask myself, What good is this doing you? Is it serving any purpose? So I would give myself 5-10 minutes to bawl then go about with the rest of my day. I think setting a time limit really helped me, otherwise I may have just stayed in bed for days on end.
I think CG is right as well. Once you get the legal stuff worked out you'll be in a better place.
