The only time you felt good in your life was when you were gluten free. Being gluten free is the correct course of action. You may also find you have issues with other foods too.
Celiac disease is multifaceted and while most people know it as the intestinal damage disease (including doctors) there can be skin immune reactions and neurological immune reactions and of course a plethora of symptoms that go with all those things.
Seeing as you aren't symptomless, I would take a positive blood test as a sign that your immune system reacts to gluten. Even if you were symptomless, and had 2 blood tests, one positive and one negative, the chances are that the negative one was the false one.
Don't feel dumb about what you did though, eating gluten again. I mean, it is something you shouldn't do and you're suffering the consequences now, but without proper information what you did was logical. In fact, when celiac disease was first diagnosed it was thought that it just went away for many people after awhile being gluten free, because just like what happened to you, they would try eating gluten again and their symptoms didn't return right away. We now know that that doesn't happen. Once you have it, you have it for life.
Thank you, for saying it was Ok for me to make the dumb mistake. Just having someone understand where I was coming from, means so much to me, truly. Thank you.
I know that gluten free is the best for my health and I intend to stay that way. I accepted it before, so accepting it now is easy, especially when the consequences are so ugly. Thank you again for your kind words and logic. I wish I would have gone on here and got some advice, before I made that brilliant move. Lesson learned.
