I have
Blood-injury phobia, which is a mixture of hemophobia (fear of blood) and traumaphobia (fear of injuries) to an extent. Basically when I see blood and gaping open wounds, I break out into a cold sweat and get so light-headed I nearly pass out. I'm fine with stage blood provided it's not overly convincing, but I can't watch gory movies. Tried Saw 3 once, and couldn't finish it.
Upside to nearly passing out when I see blood and/or injuries? People worry about me when they see me suffering. It's nice to be worried about from time to time. And if I'm hot when it happens, like when it's the middle of Summer, I cool down a lot.
I've also got Acrophobia - fear of heights. I'm fine if I'm fastened into something or I know for sure I'm not going to fall but otherwise I am terrified. The only benefit it has for me is if I'm working on something up a ladder, it motivates me to get the job over and done with so I can get down ASAP.
