I know a bit about Celiac Disease. When my son was a year and a half old, he developed terrible diarrhea and failed to thrive. In 2 years, he only gained an inch in height. After exploring several other options, he was tested for CD. His tests came back inconclusive and his results were sent to a specialist at the University of Maryland for review. From the moment he was tested, he went on a GF diet and remained on it for a year and a half until CD was eliminated as the reason for his failure to thrive. It isn't the easiest diet to follow, but it is totally doable, even more so as more items are available.
Some thoughts. . .
To know for sure whether you have CD, you need to be eating gluten (I know!) and then have the GI testing done. It's a fairly simple procedure and is done on an outpatient basis. The doctor will take a sample of your intestinal villi and look for blunting, which is one of the main symptoms of the disease.
Once a diagnosis is confirmed, you'll need to go gluten-free and stay that way for the rest of your life. There is no cure for CD. It is maintained through a diet free of gluten.
Join a support group. The folks at the Celiac support group at Delphi forums were great. Here's a link:

Many foods are naturally GF, but do be aware of cross contamination. For example, if others in your household eat gluten containing products, you'll want to have your own supply of mayonnaise, peanut butter, jam, or anything else where people dip and spread and dip again.
Eat some brownies. Yes, that's what I said. The best brownies we've ever had, hands down, were Gluten Free. Check them out:

There are many of wonderful products out there. There are wonderful cookbooks, and some restaurants and grocery stores even put out GF lists. Even Disneyland will have a chef cook you a GF meal, but you do have to call and arrange it ahead of time.
Best of luck to you!
