Anyone else have food allergy?

It's so restricting and socially limiting if that makes sense. People think 'youre just trying to be skinny" or 'you dont want to eat' or that you have an eating disorder etc. I shouldn't have to tell people that I have a food allergy. I hate it. I hate dealing with it. I wish I had help with it all, or not to deal with it. I wish there were more options in stores.
