r/thalassaphobia

Hey everyone,

I’m trying to figure out how to start overcoming a really intense fear I have of deep water.

To be specific, it’s not the water itself that scares me—it's 100% the contents. It’s that "you're not scared of the dark, you're scared of what’s IN it" type of feeling. Puddles, garden ponds, and waterfalls are totally fine because I can see the bottom. But if it’s a lake or anything deeper than 5 feet where I KNOW something is living under there, my brain completely shorts out. Even IRL, if I’m knee-deep and see a small mackerel or a jellyfish, I instantly jump back.

It triggers a total physical "freeze" response. My body goes completely cold and tight, and my mind just screams at me to escape. It even happens in video games—if I accidentally fall into the ocean in GTA, I get that exact same cold, tight feeling and have to instantly Alt-F4 out of the game because it feels like I’m about to be swallowed up.

I really want to overcome this eventually and not let it run my life, but I don't know how to take those first steps without totally triggering that physical panic.

Has anyone dealt with this specific level of physical freeze around the "contents" of deep water? How did you start building up your tolerance without completely overwhelming yourself?

Thanks!
