Phobia Of Wrists, or wrists being touched.
I don't actually know when i developed phobia of wrists, but i have a horrible fear of my own wrists.
One time at school, i fell down and someone grabbed me by it. I screamed, ran away and thought i was going to be sick.
It is hard to write with Carpophobia, as you can see your wrist next to the pen or pencil. I actually have many phobias, most ones that I think are stupid...
