Being stuck in an elevator. I try to take the stairs as much as I can, even if the office I need to go to is 10 stories high, sometimes higher.
Heights, I can try, but one time at a summer camp I was on one of those tight rope bridges. I was clipped onto a wire, so I wouldn't fall, but looking down.... and oh great, now I have to use the zip wire to get down...
I don't like being in crowded areas.
Fear of not being able to breathe, which is ridiculous, because it just makes me more nervous, and then causes me to breathe less, and cycles.
I don't like planes, mostly because of heights, and small spaces. I guess claustrophobia.
If I need to do any of those things, then I will, my body would get nervous, but my will is stronger I guess? "Even if I may die, I have to do this."
