Not to be a know-it-all, but technically fear of heights is not Vertigo, its called Acrophobia. Related to CSA? I don't know, but anything's possible in our F-ed up world.
Vertigo is a malfunction of the balance mechanism of the inner ear, which produces a sensation of spinning and falling through space. I had an attack of it a month ago, and it totally disabled me for three days, until it finally passed.
Can't be bothered with sorrow
And I can't be bothered with hate, no, no
I'm using up the time but feeling fine every day
That's why I'm telling you
I just want to celebrate another day of livin'Rare Earth
