So i think i have thalassophobia after looking up what exactly it was

So ive always used to have this niggling fear of being attacked by a shark or and animal of that nature when i've been around pools. It's mostly gone away now but sometimes it comes back when i look at pictures of the ocean or even look into deep or murky lakes. otherwise i am constantly asking the question of "whats in there" to know if i'd be able to swim. Perhaps its just another visage of "we do not fear being alone, we fear not being alone" except instead of the dark, its pools and lakes and the ocean.i guess i do have it. [7]
