Swimmimg down the rapids!

I lined up nervously to be threw  into the deadly rapids, I saw people screaming and floating away people were getting smashed around and dragged under. I was at the front of the line, the instructor picked me up and threw me into the dangerous river. I floated down with water splashing me in all parts of my face, the next rapid was coming up the instructor told me to take a breath and the second I looked back at the water I was pulled down into water. I thought to my self I was going to die.
