Shrimp, ewww

I fucking hate shrimp. im not allergic to it but my body dosent like it..when i eat it it's like my ears start feeling funny and my throat gets itchy and shit.. and soon after i eat it i throw up..it's not really the taste but it's more like the after- taste, or maybe it's the texture.but shrimp,onions,celery,cooked tomatoes and other nasty seafood like oysters i dnt like
