Ya, I am also terrified of the ocean. I can swim somewhat, but I am still terrified of DEEP waters, and I am especially terrified of being UNDER water so I definitely cannot dive head first in water like people do -_ that absolutely scares the crap out of me. I also don't like heights too much either.
When I was in Cancun a few years back with my friends, I remember I was in the beautiful blue ocean, and not very deep either. Actually pretty much only a few feet in. The waters in Cancun are very rough, and many days the "black flag" will be up which means the undercurrent is too strong to swim. ANyway, one morning I did not see the flag so I went into the water, which looked calm and inviting. WIthin moments, I realized that I was getting sucked in by the under toe. I was swimming hard and fast, but not getting anywhere (so I was basically swimming on the spot). Man I saw my life flash before my eyes. Thankfully, there was a massive boulder right beside me so I had to grab on to the slimy green stuff (which till this day I have no idea what that was) to pull myself out of the water and not get sucked into the undertoe. When I got out, I was so freaked out after my close brush with death. Right away I ran to the hotel suite though and literally scrubbed my skin almost right off because of that

ing green stuff that I had touched, but it saved my life so I am still thankful for it, whatever it was!!!
But other than that, I am Wonder woman

(just kiddin).
