Friends with Celiac Disease and Diabetes

Options
I have both Celiac Disease and Diabetes. After being diagnosed with Celiac disease I cut out all the foods that contain gluten and lost 40 LBS. Then i discovered GF replacements. I have now gained all 40 LBS back. Not sure if it was because the GF foods rate higher on the glycemic index or because I just ate too many carbs but in any case, I'm trying to eliminate them from my diet. The only grain I am eating is GF Oatmeal. We'll see how it goes. I'm interested in being friends with others that have the same issues as I do.
