i picked my face and skin for 5 years, I used to have beautiful skin and now it is covered with scars. I could not stop picking and it was an anxiety issue, sometimes I could not wait until I got home and I would go to the toilets at work and emerge much to the surprise of my coworkers, red and swollen and usually bleeding. I stopped this behaviour by using CBT in combo with a rubber band around my wrist which I used to flick, quite severely when I felt the urge to pick. So no I do not think you are alone!!
Interestingly enough my flatmate would pluck her eyebrows to anihilation and had a huge gaping hole in which she claimed was an ingrown hair, but in reality she picked this spot the most. Try CBT it really did work for me.
