I'm terrified of sharks, I don't even dip my toes in at the beach

I watched jaws when I was three while being baby sat, my fear of sharks also prevents me from swimming in pools or being in spas at night - even if it's well lit

and even though sharks don't use spas or pools
And hopefully I don't offend anyone, but I'm scared of amputees, I'm terrified of becoming one, and I'm scared of projectiles, so things that could flick up in my face, I don't go near, and I don't use lawn mowers or power tools :/
I have this weird thing where I can't sleep on my back with my head to the side incase someone comes into my room and deliberately kneels on it (my head) or accidentally sits on it - causing my neck to snap.
Oh the shame
