In preschool, I was playing on the playground (relitively tall one too), and when I was walking on the monkey-bar stairs (you all know what I'm talking about) I slipped off of one and hit the back of my head on one of the bars and cracked it open. I had to be rushed to the emergency room, and the white shirt I was wearing was turn red, completely soaked in blood. I had to get staples and I still have the scar today :/
In July, a few months ago, I was on a trip to Wisconsin. We always swim in the lake, and I'm a really good swimmer, so I would dive off of the boat and touch the bottom of the lake (16 feet below). When I came back up after doing that, I had a panic attack and couldn't swim for like 10 seconds. I finally regained myself and swam to the surface, where I then climbed back into the boat and sat there shivering for an hour.
