It doesn't mean you wont ever be healthy again. It may be that you need to explore other treatment options with your doctor, and sometimes changing up your diet a bit can help. I, for example, am vegan because everything from animals just destroys my digestive tract. I'm sure you probably already have tried cutting out things that mess with your stomach, but maybe some experimentation with food will help at least some. I'm not saying you have to be vegan or anything.
