Scared of water slides, and going to hurricane harbor tomorrow?

I'm a big wuss. i'm terrified of roller coasters except of baby ones like ninja and space mountain. I'm scared of home water slides too, but i eventually go down them, and i'm fine. i've been down an exceptionally high water slide in henderson, nevada, and i liked that one. i wanna know what slides i wouldn't freak out about :/ i don't like the idea of covered slides either..
