I have also been allergic to all seafood my whole life. I eat Vietnamese, Thai and Burmese cuisine, though. I realize I am probably eating fish sauces and dried shrimps, but for some reason, I rarely get affected. If I do have an effect, it's only a little bump on my lip or slightly scratchy throat. As long as I'm eating the foods in these forms, the amounts seem minimal enough or transformed enough from a whole fish or crustacean, that I have never had a serious reaction. When I've accidentally eaten even one bite of a more whole fish dish, e.g., a whitefish dip on a cracker, my throat starts to close up. Good luck!
