Thalassophobia has been my number one fear since childhood and when I found this sub i thought it would ease it a bit. But after seeing everything here I think I can't even jump off a lake dock anymore?

Got my fear as a child when i was retrieving a floater in the beach that strayed too far and just before the water was up to my chin, I slipped under where the floor had a quick drop. I never learned how to swim so this was panick material already. But when I sank just below my head, my feet sank into a thick patch of slimy seaweed, and being the crazy child imagination machine I was, I immediately imagined stepping on some weird sea creature's back. Is an experience like this how some of you triggered this phobia? Does this sub make it easier for you?
