Help I'm sopposed to be leaving in about a half hour to go with some friends back to their school 4 hours away. I'm so nervous that i now really don't feel so well. I have gas and some nausea. I also feel really cold, no temp. Am I possibly sick, or so nervous that I made myself sick? Should I go? Will I have fum if I do? I am Ibs-c and it is not all thay under control.
