Ok, so I can't help with the anxiety, but maybe your doctor can give you some nice little pills that might make it easier.
As far as the traveling with CD. I have the big D and it is a huge concern for me when traveling for all the reasons you stated. I'm assuming you are dealing with D and not C so disregard everything if I am wrong. Depending on how severely you are affected there are a number of things you can do. Try immodium OTC. I take up to 8 a day on a regular basis, because I won't take Questran unless I have to travel. I do have Questran that I take when I have to travel, but I have bile salt issues. Probably can't get a Rx for that if you don't have bile salt issues. You might be able to get some Lomitol (sp?) that would make traveling easier. Also, I started taking Xifaxan about a year ago and it made a huge difference in the number of trips to the bathroom a day. basically cut my trips in half. It is an antibiotic for travelers D that is used off label for CD. You might be able to try that even for a month or two just as some added insurance while out of the country.
My last suggestions, while not pretty, would give you a little security. Wear some loose clothing with adult diapers underneath. That way, if the worst did happen, at least your clothes would stay clean until you could get to the bathroom.
Oh and if possible, I would try the meds in advance. You don't want to find out that lomitol stops you up for days and makes you miserable on the trip of your dreams. Better to find out at home so that you can play with the dosages to find a happy medium. Just enough for safety and comfort.
And congratulations on taking the trip of your dreams!
