I hate heights. As soon as I can see how far away the ground is, I'm filled with this uncontrollable fear and urge to get down -any survivable way to get down is better than this.
My captors seem to find my fear interesting, as if they have something to gain by studying me. They leave me at some altitude and then show me how far the drop is. How terrifying! Then when I try to get down, they try to stop me! Well, I'm getting down any way I can, and any attempts to hold me back will only slow me down.
This fear really is a problem. Sometimes I've gotten so determined to get down, I've hurt people in the process. My captors recognize that too, and hold me back even more. Then when I make it to safety, they bring me right back up to do it again. Can't they see I want to get down?
Who/What am I, and what do they call my fear?
Hint 1:
The larger the drop, the greater the fear. My fear is entirely based on how big of a drop they show me.
Hint 2:
The term "altitude" is used more figuratively than literally.
