New to site and first time seeking help. Mine has morphed into other more harmful behaviors.

I am seeking help from you all with my picking of cuticals and nose to the point where they bleed. Ihave picked just about every part of body at some point in my life. About a month ago I had a moment of clarity. I self determined that the picking was infact self mutilation. I belive that underlying cause what ever underlyes this disorder has also progressed to the point where I abuse drugs. I have sought treatment for the addiction. It was acouple of years ago. I got clean and back on track. I lost my job for unrelated reasons....and began using again. I am seeking what I am beginning to believe that the picking is hallmark or indicator of a deeper phychological problem. Any help is greatly appreciated. Thx
