So I have a past with always thinking something is wrong with me, or when something is wrong with me I make it seem way worse than it really is. Recently I have been worried constantly about my health and believe it is affecting me all over. I have been very tired and also have been getting stomach aches and diarrhea for the past 4 days. Diarrhea after I eat meals. In my mind I can't decide if I have a serious gastrointestinal issue or if all this worrying is just causing my stomach to feel this way. I don't know what to do.
