How to get over the fear of drowning? Because of it, I was too afraid to learn how to swim.

Go with a strong swimmer to the pool, and have them teach you a couple of basic things, namely how to float on your back, and how to doggie paddle. I know what it's like to have the fear of drowning, but in me it manifested as a general fear of water slides/rides. I taught my self to swim shortly after the last time I almost drowned, 27 years ago. And, have them teach you in the shallow end of the pool. Are you ok with water? I've never minded water, just water slides and rides!
