Fear in the water

I want to learn how to surf very much, however I freak out in the water. Today was my first time far out on a board, and I was knocked off one time and thought I was going to have a panic attack. I have this obsession with sharks, and I think this has tainted my view of the ocean.
Anyways, has anyone experienced this? Is this something I can eventually get over? I understand that statistically shark attacks are rare, but I guess I just have a fear of the unknown or something.
I live in HI, and it would be a shame if I leave here without learning how to surf. Thanks for any input!
