I'm feeling very frustrated. Some of our friends are just not getting the fact that I can never eat gluten again and can't get into their head it's an auto immune disease not an allergy. They have asked us to go for a carvery despite knowing my situation. "Why can't you eat a carvery??" My husband explained " because of the really big risk of cross contamination" It's just not safe" "My wife had gluten problems and she had her gallbladder removed,now she can eat it" I feel like banging my head against the wall seriously. How can I make them understand?
