The worst thing probably was something physical that happened to me.
I was about 14 at the time, and in high school(grade 8, I live in Canada so no middle school), in the middle of winter (December, -25 weather, snow/ice everywhere etc), and was outside the back of my school with a bunch of my friends at the park. I bent down for a second to pick something off the ground, and got hit in the face with a metal teeter totter(or see saw wtv), that was all ice. I kinda flew back, got knocked out for two seconds or so, and just ran into the school holding my face where I got hit, blood gushing out of a cut around my eyebrow where it had been cut with ice. Long story short I go to the hospital, my entire left side is pure purple, swollen like 2-3 inches, and my eye is swollen shut. Lucky for me, I didn't shatter my eye socket or have any sort of brain damage, but I've never experienced pain like that ever before.
This happened on a Friday and my parents still made me go to school on monday >_> I still dunno who did it either
