First off..sorry to hear about the dx and your insurance problems. The thing to remember though, like Nanners said, it isn't a death sentence. I have had CD for 21 years now. I have my good days and I have my bad days. Right now I have horrible pain in my rear and I sit most of the day for work. But I always remember that things could be worse.
The thing to remember is there are a lot of people out there like you, and a bunch of us are here to support you. It is ok to be stressed and worry about it..so go ahead and be stressed for a little bit. You have to go through that process some times. Next, remember that it can be managed and things will come together. It seems like you are on top of things. You have a doc that seems to be on top of your illness and will try to help you.
I hope you feel and get better soon and don't be afraid to come on here to vent. Things will get better..don't worry.
