Thank you all, I'm glad to say that I'm feeling less anxious and able to think a little more clearly now that I've stopped eating wheat now. The only person who has dismissed my food intolerance is the CBT counselor I am seeing, who is quite certain that my symptoms are caused by depression and not food, needless to say, I haven't bothered continuing the discussion with her because it was quite clear after one session that she would not be swayed from her belief. Talk about inappropriate bias from a proffesional. I am quite sure that at large number of people with anxiety and depression could be helped by looking at what they eat!
My apologies for putting my post in the wrong section, I initially intended to ask friends and family how they initially reacted to discovering their loved-one had coeliac, but in my hazy, foggy, anxious state of mind didn't quite know what I was doing at the time
I would think about getting a new therapist. Yes, they "only" deal with emotional problems, but the good ones will recognize that physical illnesses can have things like depression and anxiety as symptoms, sometimes the only symptoms. In fact, it was a psychologist friend who first told me to consider vitamin deficiencies, perhaps caused by celiac or something else that causes malabsorption, and that he didn't believe that I ONLY had problems with depression/anxiety.
Something like that (that she doesn't believe that food intolerances can lead to symptoms, even after you told her that it does do that to YOU) is a major no-no for me in a therapist and a sign that they should be fired, if at all possible.
