I’m terrified of open water and that’s why I’m scuba diving

You know when you’re swimming and something touches your foot, and for about 5 seconds your heart is in your throat and you feel a wave of panic wash over you? That’s how I feel, but constantly in open water. I’ve been snorkelling before. That was fun. Until I swam to the edge of the reef. The water temperature changes from warm and pleasant to icy cold and the reef drops into darkness – into the unknown.
