I think when it comes to heights, it's a rational fear. Fall from somewhere high enough, you know it will result in pain or death. ^^; As to vertigo: it's that feeling of being off-balance. Not sure if headaches are common with it too, but for most it's just overwhelming dizziness.
ah yes, dizziness, that's a better word.. but i've heard people that are diagnosed of having vertigo that made it seem like a really accute one, like they need to spent time on bed or hospital because of it..
A prank that totally went wrong that happened to me when i was little which ended up with me getting a scare in my forehead
traumatic experience? that certainly triggers it..
And I know it's mainly cuz most of my family (with the exception of my mother) has conditioned me to believe that I will always fail no matter how hard I try, so...yeah.
i wanna ask why whould family members be like that, but that seem like too private.. i kinda get the feeling, while my parents don't go as far as that, i always feel they're not being supportive, or didn't understand me at all, hence i was always misunderstood, sometimes felt like i'm being underestimated.. as if they don't understand people have different personalities, different taste or ways of looking at things, and in my family, i'm the only one who are different, sometimes i feel i don't belong, even to thought that i'm actually one of those with special needs..
truth is, things like that should motivate us to prove ourselves --to us most importantly..
I think my greatest fear is myself. You know how we all have that part of ourselves that's bad and wants us to do terrible things? That. Because that little voice has always been really loud for me. And the thought of one day giving into it and doing something I'll regret for the rest of my life scares me. I don't want to be a monster.
i think this relates to fear of responsibility or failing.. we fear the outcome and what if it doesn't go as what we think it would.. i don't know about how bad the thoughts are, but i've thought about those kind of stuffs and i fear it may not worked, cuz everything has it's consequences.. now change all that to having good thoughts and we still fear of the outcome, that's fear of failing, in the end ourselves is the biggest obstacle, most of the times ourself is the limitation preventing us going further, we don't dare take risk.. i'm a lazy, moody, indiscipline person, i might know this..
just,
@Shadow whatever those evil thoughts are, don't do it will ya? lol..
Oh. my. goggies. "Daddy Crane". I'm going to use that forever now. If I ever fall into Batman-verse and run into Scarecrow I'll be like "hey, Daddy Crane, what's up?" And then I'll be fear gassed. But it'll be so worth it. 
You're probably referring to Gotham, though, but still. Ooooooohhhhhhh, Jooooooooooon.... -begins the hunt-
