Glass/see through steps make me anxious. I can force/choose to go on them, but I become anxious. I absolutely won't go on those glass bridges, though, I think I'd die.
Most reptiles give me heebie jeebies.... ughhh...
I am with you on falling, Kim. Not as severe, but I often experience some 'imaginary falling' that makes me so anxious, the worst ones are when it happens while I am laying flat on the bed sleeping.
