Me? I'm scared of 99% of everything, both rational and irrational.
I've got a paralyzing fear of heights - like, I get shaky and start crying when someone else crosses a rickety suspension bridge, is how scared of heights I am - I'm afraid of dogs of a certain size (like, labradors and up), and I've got a deeply rooted fear of screwing up, in any kind of context - just to name a few.
I am a shaky bundle of fear, is what I am.
