I get what I can I can only describe as a nervous stomach. I cant seem to work out a pattern. First I thought it was gluten, then sugar. Doesn't seem to be those. I get it with some stressful situations and I am getting more and more anxious all the time. I get extremely nauseous and quite often diarrhoea but I spend lots of my time nauseous. I've just had to hurry home from town (30 min journey) convinced i wasnt going to make it home. This has really upset me as I was convinced I was going to soil myself on the train. Anybody have similar? What can I do. I have visited the doctor several times. Ive had stool samples which did flag something up so had endoscopy and colonoscopy so all serious stuff has been ruled out but don't know where to go from here.
