I can't swim because I have a strong fear of water. Look back at my childhood experience, I think that three reason might explain the fear. The first  reason is why I was not allowed to go near the water. When I was a child, my mother had unreasonable fear of it. So, as a child I was taught see the water as something danger. Second, my eyes became bad ones when I was five. If I took off my  glasses in the water, I couldn't see anything, but this increased my fear. The worst part of your experience is that as a child I see a neighbor drown. Since then I have been more frightened.
