Is it normal that i hate when my wrists are touched?

I hate when my wrists are touched by something or someone other than myself. I hate it because my wrists are very sensitive and every time someone or something touches my wrist, I jerk my hand away and tuck it between my legs, or under an arm to make the feeling go away. I have to squeeze it between my thighs or in my armpit or the crook of my arm to make my wrist stop hurting. It feels bad on different scales though. If something harder or sharper touches my wrist, It feels like my wrists have been slit, and I start having an axiety attack, Hallucinatory type episode. If something not as hard and not as sharp touches it, I get a rush of energy and I shiver, and I usually slap or scratch or jab at the person(or object) that did it. For an example, today, my friend had tapped my wrist with a pencil to get my attention and I jerked my hand away and bit my lip and craddled my wrist in the crook of my arm, complaining about how it hurts, and she just stared at me with an expression that said "What the crap is wrong with you?"
Anybody else have any experience like this with their wrists?
