Phobia of breaking bones

I have a terrible phobia of breaking bones... seeing anyone break them, breaking them myself. If i'm watching a film and someone breaks a bone in it I usually either pass out or feel the urge to vomit!

I actually get friends to watch films for me before I do so they can tell me if and when someone breaks a bone, just so I know when to fast forward or leave the room. Luckily they're understanding about it!
