Hello,

Try not to get too down about the diagnosis. I learned that I have gluten-intolerance/celiac two years ago, and the diet is very manageable once you have the information on which foods to avoid and where to find the carbs that you can have. Acclimating to celiac requires:
1) learning the list of ingredients/foods to avoid
2) proper planning (ie packing of lunches, etc).
3) a bit more hunting at Whole foods/specialty stores/websites for your allowed carbs and paying a bit more $$ for these foods

At the end of the day, the extra efforts and planning will pay off, because you will feel fabulous on a GF diet. Who knows, athletic performance could improve once you are absorbing your food again. Mine did.

In terms of carbs, you don't have to give them up. Substitute flour derived from wheat with flour derived from rice, corn, garbanzo beans, tapioca, etc. These flours can be purchased in most stores (even major grocery store chains). For a bit more money, purchase pasta dervied from rice or corn (again, sold almost anywhere). Most these pasta brands taste great. There are numerous brands of chips that individuals with celiac disease are permitted to eat (just read the labels carefully). And you don't have to give up cereals or english muffins...just find gluten-free section of the market.

Keep your chin up.
