whenever i get nervous about anything (which is Everything), I get nauseated, upset stomach and, most often diarreah. I worry about rural car trips, and it seems as though the more i worry, the more i feel i have to go. Like my mind has literally trained my braiin into thinking i am going to be sick just based on the very thought of it. Is this normal?

Is this normal? It is for people with ibs. I have had it for years. I know mine is directly related to anxiety and stress. My ibs has gotten better since going thru the program. As I take care of myself and lessen my anxiety my ibs is better. I have read the book called Irritable Bowel Syndrome and the MindBodySpirit Connection. I recommend it. Can't hurt to learn a bit about something.
