The fuck is wrong with me?

So, I have a fear of dark water and touching fish. Not seeing what could be swimming around under me blah blah. Thing is I also love the water and fishing. I would like to live on a boat. Now the water thing is understandable but the fish? Not sure if its how they look or what. Ive hunted boar with a spear and knife and had to grab it to finish it off. Ive hunted deer, alligator,rabbits all kinds of animals and fleshed them and chopped em up. So why do fish weird me out? anyone else with this problem?
