I wouldn't place too much emphasis on the 30 day timeline - it's just too short to turn things around completely. Well, crazy stuff can happen, but I would encourage you to drop expectations below zero - in the minus territory.
Also, D is not the end. You control when you are done. D is a piece of paper. I am sure some of the vets will come and give some good feedback on that.
Take the D out of your mind - I know it's hard. But it's only time for you to take stock of yourself, healing, and getting your emotional and mental sanity back.
Sorry being harsh about the 30 days, but needed to be said.
