I almost died from shock once.
When I was four years old, we were moving and I kept running around between our old house and the moving truck.
It was early in the year and it had snowed that day, so I was busy collecting snow and building tiny snowmen. I kept crossing the bike lane to get to the parked cars with more snow on them.
At one point my dad pulled me aside and told me to be careful when crossing and to always look left and right in case there was a bike coming and let them pass before crossing, and I did.
Next thing I remember is lying on the walkway, looking down at my feet and seeing the wheels of a bike going over my legs one by one. My mom says my wail was so loud she could still hear it in our old flat on the fith floor.
My dad reached me first and I told him that I thought my leg was broken and he (probably thinking I was being a bit dramatic) tried to soothe me and put me on my feet.
My bones just crashed and the two ends slipped next to each other and the upper part of my shin pocked out from under my skin. I still have a scar there.
I still remember feeling very betrayed because I had looked left and right and saw no one coming. The woman that ran me over appearantly came out of a drive and ran me over at full speed. She hightailed out of there as soon as it was apparent that I was seriously injured (I guess she saw a lawsuit coming her way).
Anyway, my parents put me in the back of their truck and drove me to the hostpital while I was in the worst pain of my life and wailing quitely. In the hostpital I don't remember much aside from the neon lights on the ceiling. Then I have a pretty big gap till waking up in a hospital room.
Appearantly what happened is, that when my parents arrived with me in the ER the nurses just put me on a gurney to wait for the next available doctor and forgot about me for the next two hours or so. By that point I was going into shock and was going in and out of concoiusness. My parents tried their best to prevent shock and keep me concoius, but there's only so much you can do. They finally sent a doctor when my dad screamed at them that I was stopping to breathe every so often.
They gave me an infusion, reset and bandaged my leg and I was fine again, but it was a pretty close call.
