I am highly allergic to all nuts (insert lame joke i’ve heard a million times) the worst one is pistachios for me.
As a child I ate peanut butter and jelly sandwiches a LOT. It was my most favorite food according to my mother. Then one day she gave me a sandwich, walked in the other room, came back and I was covered in hives. Ive been allergic since.
I am lucky however in the way my allergies work, I generally have 20–30min before it hits me bad so I have a grace period to get some sort of medicine into me before i start vomiting and my throat closes. Thankfully im not like the people who can kiss someone who ate nuts 4 hours earlier and then drop dead.
