My diagnosis has been "anxiety" also. Weird though since flying doesn't really bother me. Guess it's just the worry of missing a flight due to delay through security these days. Lots of things for me trigger anxiety lately. I'm going to a doctor that I used years ago for possibly Krohns (thank goodness it wasn't that) next week and he already has my test results from my recent doctor. The one I'm going to next week is supposed to be the best in my area. Only reason I didn't use him for the colonoscopy that I had back in May was that he didn't use the pills that you can take now. Only the liquid stuff of which I can't drink. I throw it up no matter how hard I try to keep it down. He now uses the pills.
His receptionist also told me that I would not have to have the colonoscopy done over, so that brought a huge smile to my face.
