"Guess it could be worse couldn't it?"
You've said a mouthful there! My daughter has alopecia aureata - another autoimmune disease - in which you develop patches of baldness (and gluten intolerance is correlated with this, so she's thinking about whether to treat for gluten intolerance to see if it helps the alopecia!)
Anyway - I told her that in the spectrum of autoimmune diseases, alopecia (or, here, gluten intolerance) is the one you would pick if you had to .... At least you can do something about it. There are many autoimmune diseases for which there is little to be done (as in MS...)
And once you learn about the new ways of cooking, there are so many good alternatives to the mainstream wheat flour products.
