I had brain surgery nearly 3 years ago, and have developed phobias since then. I am afraid of heights, even on tv, and afraid of tall things, like a tall building, or, when we used to go to the Gulf, we would drive by the USS Alabama. I can't even look at it now, it makes me sick at my stomach. Just the size of it. And I used to be a competitive swimmer. I have been swimming, and thought I was drowning over the deep end. I can't go swimming any more now.
