DNS my first Oly Tri but found a new term for my fear of Open Waters : Thalassophobia

Couldn't sleep the night before my first Olympic Triathlon because of the fear of getting into open waters. Ended up spending the night googling about this.
PS : I had attempted 2 unsuccessful open water swims before this (with tow float and a group of open water specialists). I can swim 3000 mts in the pool but I’m scared of lakes and open waters.
