I've asked this question several times, but please help? Desperate 13 year old?

For a 13 year old, you certainly have an advanced command of the English language. Most 13 year olds I know can't even formulate complete sentences, let alone capitalize and punctuate correctly. But, from everything you've described, I'm also suspicious that you have Chron's Disease. Nobody can diagnose you over a yahoo answer board, but your symptoms are, for the most part, consistent with Chron's. This can be a bothersome condition that can flare up and then subside for awhile, so you may notice this condition tends to come and go. It can also be very frustrating to treat, and you may not be successful in getting long-term control over this. For now, if you are seeing a good Gastroenterologist, you're doing just about everything you can do. If this IS Chron's, then you may be in for a lifetime of problems. Let your doctor poke around and see if he can come up with a better answer. Or, you might consider a trip to someplace like the Mayo Clinic for some advanced studies. I can't tell you that it would help, but at least you would know that you've done everything you can to get relief. Good luck. Oh, and consider a career as an English teacher.
