For me, I wouldn’t really call it a desire or wish to jump, but more a sense of being pulled over the edge. I am not at all suicidal and would sure not like to die like that, but it has always puzzled me, that pulling sense. I have a fear of heights, too, but that doesn’t always stop me from looking over the edge with a sense of excitement until my live-saving fear kicks in. Always listen to your fear!
This is bad general advice. Good for specific situations of imminent peril, bad for interacting with the rest of humanity.
