I have realized I have a wheat sensitivity and have stopped eating most things with wheat/gluten (tested by eating part of a delicious baguette after going completely wheat/gluten free for a month and the resulting intestinal response was as swift as it was ugly). It is, of course, nothing like having celiac disease, but I have been having a lot of fun playing around with gluten free foods. I am using a lot of almond flour (from my home made nut drinks) and a lot of chick pea flour. Plus these rather tasty brazilian cheese puff things that are made with yucca flour.
My niece has celiac disease and after they got the house sort of straightened out (and got one of the siblings to stop trying to torture the one who can't eat gluten by eating pizza in front of her) -they seem to be doing fine with it. Even my sister in law who can turn any small thing into armageddon type of disaster scenarios with her as the victim/hero, has had to give up the martyrdom stance on how to feed her child who has it (reluctantly and she swiftly went on to some new thing she could climb on the cross about).
I know it won't be fun to deal if it is celiac, but I would be happy for you if it was not one of the even worse scenarios.
