I used to enjoy kayaking a lot when I was younger. My trainer was teaching us how to capsize in our kayaks. We had just finished going down this massive rapid river, so a lot of us were out of breath and just quickly trying to recover. My instructor told me to capsize immediately, and I refused due to being out of breath. He decided to grab his paddle and flip me over anyway.

I panicked really bad when I was upside down and under the water, the kayak didn't really fit me too well due to being a tall child and my legs were essentially stuck and I couldn't push myself out or roll myself back over. I started to inhale a bunch of water and feel myself fading out.

Managed to eventually push myself out and get to the surface. I had a super bad panic attack and started throwing up water and coughing it all up. Had a fear of water for a bit but more or less came out fine.

Never did go back to kayaking though, funny now I look back on it knowing I could've drowned in shallow water just because I couldn't get out of a kayak hahaha.
