I have a dilemma with Thanksgiving coming up. My MIL is making dinner and we're bringing mashed potatoes. I was fine with all that until I remembered that I have several food allergies (peanuts, tree nuts, coconut, palm are the major ones) and have had a major reaction every time we've eaten at her house. Now I think she's doing gluten free for her daughter even though she could care less about my allergies and it worries me because most packaged GF foods (it would kill her to use fresh ingredients) contain major allergens for me.

So my dilemma is...eat it anyway to avoid causing a scene, then suffer? Or not eat it and let the whole family harass me? I brought my own meal to a family gathering once and they were weird about it, not that I can bring my own Thanksgiving dinner. Asking her to be more careful is not an option as we've already tried and she will only make an effort for her daughter.

(I should add that the last time we had Thanksgiving at her house I had a reaction that lasted three days.)
