When I was alot longer, like 7/8 and had a few things going on in my life that made me feel unhappy the first thing that happend rather than get upset was to go off my food and feel sick after eating even the smallest amount, it could well be the same with you and if you're getting upset/nervous by something it could lead to a build up of acid in the stomach and eventually lead to being sick which is what I'm told effected me.
