I was shocked to find out that this is an actual disorder. I've had some of this symptoms for a while now like pulling out my hair compulsively, picking at my skin (arms and legs specially) and I even cut my skin once :S. I found this site on StumbleUpon and read about it by coincidence.
I guess the obvious step it's to get psychologic help and I will, but as I know me and I tend to procrastinate everything by lack of time is there anything I could do in the meanwhile? I don't want to get more scars on my arms...
