Random soy allergy popping up, how do you function with this???

So a few weeks ago I started getting hives all over my legs and having a very itchy and bumpy chest neck face back area, it was pretty miserable but started to test certain common food allergies by eating things first in the AM and seeing what caused the hives. Dangerous, I know lol.

Gluten, wheat, dairy, egg, cheese, all fine. Background is I’ve worked in restaurants my entire life and I usually have a pretty good understanding off food allergies, so I was careful not to inject anything for a few hours each time I tried this method. I don’t have health insurance so this was the best I could do until I can save up funds for an official test. Finally soy, as the only listed allergy, literally just had some chickenbroccoli with soy sauce, used a lot of soy sauce as well, nothing else other than salt pepper garlic(that I’d already ruled out)

BAM

Huge hives, all the itches, damn it.

So my question is, how do you live like this? I work 10 hour days in a bar, I eat out more than I should, how do you function like this and go to restaurants and stuff??? Obviously I’m not gonna die but man do I hate the hives and itching. Nothing else has reacted like that really. Also as a side note I literally never noticed… soy is in everything!!!
