I haven't gotten sick (thrown up) for over 8 years, In January I was sick twice for a couple of weeks, always on the edge and about to get sick, In February it went well and I was not sick until now.. I do have an upset stomach again and I am scared for some reason to throw up if I have to somehow.. I'm only 17, the last thing I ate was a sub sandwich which had chicken breast, onions, cheese and mayonnaise on it, the only medical condition I have is iron deficiency but it can't be why I have been feeling like this, I believe it is the sub that's bugging me, but can anyone please tell me that's its okay to get sick? How can I convince myself it is okay and get over that fear? I also hate it when you get sick but there's nothing in your stomach.. please I need some advice! =(
