YES I am constantly worrying. Even when I was little, I would literally fear for my life. I wouldn't ride elevators because they might break, I hated getting my haircut because the scissors were to close to my ears, dont even think of putting me on a rolller coaster.
I have improved a little since then. I try not to have irrational fears, but I still get scared. I hate to dissapoint people, so when "my best" isnt what was expected of me, I get really scared.
