Onions being a trigger is so hard

Ever since i was a kid i could not stand onions. Everyone kept pushing me to eat them because "they make every dish better and you won't even notice them" until one day i had a meltdown because it touched my finger (i was literally washing my finger all the time and crying, I was 8 years old), i couldn't take it anymore and told them i will never eat them again. It doesn't matter if i can't feel the taste, i can't stand the sight of them or their texture either! But unfortunately so many dishes have onions and whenever we go out or when i visit another house, i get so anxious that i won't find anything to eat without onions and i feel so bad when we visit others for a meal because I'm so much trouble due to being unable to have onions in my dish. I have a very restricted diet but nothing causes as much trouble as onions
