I think that under reacting to situations like this is human nature. As an adult, I would definitely call 911 and deal with the repercussions after. As a child and teenager, my parents definitely just made me shotgun Benadryl and hopes for the best. I think judging a 17 year old based off of what most sober and rational adults would do isn’t fair.

I have a life-threatening shellfish allergy and only have epipens that expired in 2016 due to cost, so ymmv ¯\_(ツ)_/¯
