swimming

Today we have a swimming class. I entered the water but I don't swim. I am afraid of water because that I have a terrible experience .When I was a child my family took me out to go to the beach. I sliped incautiously. I remerber I was scared and burst into tears. Then I don't want to enter the water anymore. So I am incapable of swimming. I am afraid that my head enter to the water beause I don't feel a sense of security. My P.E teacher told me relaxed my nerve. Tried to let my all head enter to the water and give out breath slowly. I did all my can but still be choke. I felt very uncomfortable and almost cried. Then teacher told me to take a break. Next week again.
