tjcran, I'm sorry that anybody has to be here. I was in incredible pain 3+ months ago (hard to believe it's been that long) and still am to some degree.
If you're still in communication with your W, it is imperative to follow the DR rules. I would really recommend getting a coach here STAT, because they can fine-tune to your sitch. You'll hear a lot of the same stories, but everyone winds up in a different place.
To tell you how to work through this, I can't. Losing weight? It's called the DB diet. I weigh a bit less now than I did in high school. It's pathetic. Like CWOL says, melatonin helps for sleep - but don't overdo it. Exercise, and then do it again. Get those endorphins working. And, GAL. Find other activities, things to do. Show that you can survive well on your own, in spite of what you may really feel. We're pulling for you.
