I don't mean to be discouraging, but I know someone with Celiac, and it's harder to control than you might imagine. Cross-contamination of gluten is a serious concern, and very few restaurants really understand the risk, so it makes it difficult to eat out even if what you order does not have gluten as an ingredient. If it does turn out to be Celiac, just be very careful until you get a handle on what's safe and what isn't. You'd be surprised what all has gluten in it. "Natural flavors" can even mean gluten in some cases.
Nevertheless, I'm glad to hear you might have a diagnosis.
