My thoughts? Try reality.
I don't mean to sound harsh, but celiac is a real, physical disease. Everybody, and I do mean everybody, has something to contend with. We can't wish it away. We deal with it. The way we deal with it can strengthen us and make us better people, or it can weaken us and put us into a world of denial and wishful thinking.
I have faith in God, but I don't ask Him to deliver me from my ailments, I ask him to give me strength to deal with them, and I thank Him that they are not worse. And when the time comes that I DO have worse to deal with (an inevidability in this life), I will handle it in the same way.
