I don't know I do have some crippling social anxieties from time to time, but I'm not really especially afraid of anything that I can think...Actually I got one. Bodies of water, swimming, and shit like that I guess. Even just dying by drowning is a harrowing thought. I don't often frequent swimming pools and I've been virtually land locked all my life so that's easy to forget. It's something I do think I can get over to some degree if I stayed in a coastal area long enough, and maybe actually got an some boats/ships...but.
I bet I'd have a proper freak out/ sea sickness, and all kinds of paranoia if I ever sailed to where you can't see land or something like that..
