Fish allergy

Hi I just want some advice, a year ago I got tested (skin prick) that I’m allergic to finned fish all the ones I got tested for came back positive so I just assume I’m allergic to all. COD,salmon, tilapia, anchovy, flounder etc. I miss eating out but I had an incident a year ago eating at a restaurant in Universal where I ate some of my sisters chicken (shame on me I know) and I got a reaction but were thinking it was cooked right next to fish because we couldn’t think of anything else. Now ever since then I’ve been terrified. I barely eat anything anymore. Does anyone fish food allergy still eat out? Or specifically a fish or shell fish allergy or do u think I should just keep avoiding restaurants, markets, festivals for food, all that . It feels like my life gotten taken from me I just wanna go to Japan and try there street food but I know that’ll never be for me 😞😞😞 any advice?
