My yoga teacher and I had a discussion about choosing not to react just this morning. She often says during our practice "your body will react but your mind does not have to."
So I am working on just taking a deep breath before I react and try to make the right choice.
I totally understand your frustration about traveling..I used to do the same, camping, hostels, third world countries..it's all become too daunting. I did make it to Australia for a visit last year, only hard because of the long flight but worth every second. I was reading somewhere the other day about a girl who takes her Enbrel on camping trips in a cooler. Its takes planning. No more sleeping on crappy floors or mattresses for me though!
