What's Wrong with Me?

So I've been feeling really crappy here lately, off and on basically since school started. I've been sick off and on, and I've never been like this before. It seems like it all started happening after I was diagnosed with Celiac disease, but I don't exactly know how there could be a connection to the two events, as theoretically I've always had Celiac disease, and being diagnosed just meant that now I know that I have it. This school year I've had a few colds, which I don't normally get. I also had a case of shingles about 2 months ago, which surprised the school nurse because apparently young people don't usually get that unless their immune system is really over-taxed. Looks like my immune system is working overtime and failing. I also have trouble getting enough sleep, but not in the usual way. I can sleep for 10 hours straight and still wake up feeling tired. I've also been told that I grind my teeth when I sleep, so I am apparently stressed. Well, the culmination of all of this came on Monday when I went to the health center here at school. I thought that maybe I had mono, and so I asked if I could get the test for it. I was told that I would have to come back later when one of the nurse-practitioners would be available. When I came back and saw said-nurse she said that she didn't think I had mono, but wanted me to get tested for anemia and possibly thyroid problems. She said that perhaps that Celiac had led to anemia, because basically when someone with Celiac eats products with gluten in them, the gluten wears down the villi that normally absorb nutrients and such in the intestines. Thus anemia can follow because if the villi are worn down enough, iron among other things can't be absorbed. So later that night I went and got 3 vials of blood taken to be tested for mono, anemia, and thyroid problems. I'm still waiting on the tests to come back, but I almost don't want to know the answer. It seems like every month some new problem comes up. I feel like I'm falling apart. I used to not get sick, but now I'm sick and not feeling up to par a lot. It's like I've finally discovered my Kryptonite.
