Zit Picking Arms, Face, Shoulders-Squeeze, Dig, Repeat.....

I have just about gone over the edge picking my shoulders to pieces. I pick my face neck shoulder and forarms. I just thought this was something I did until I came across this website. I search my skin until I find something and then go after it until something comes out. I use tweezers to remove the plugs that do not willing leave and will attack that spot until it bleeds like crazy. I will remove something. It's like I have to be in control of something and this is it. I know it is bad and unhealthy but it is somewhat soothing at the sametime. The things I pick at have something that comes out so it started as a beauty reason but has snowballed into this thing that causes me to hid my arms all the way down to my wrists. This habit started out on my face about 3 years ago until I started doing serious damage, and it made me miserable looking at my face. I have managed to keep my face picking under control but only because I do not want to damage it any more. My arms are my new victims. It is a larger area than my face so there is mor skin to scan. any over the counter acne product only made it worse. I use kosher salt in the shower and it somwhat helps. I know this is in my head . I see other people that have the same skin bumps I have but they do not destroy their skin trying to remove the goop underneath. I know the first step is to acknowledge that there is a problem My main problem is that I will have episodes where I will attack my skin and then leave it alone because I have hurt it so bad, then when it is about half way healed I will go after the spots again to remove the rest of the goop, thus causing a worse scar and longer healing. This causes keloids, thickining of the skin as it tries to repair itself by producing massive cells quickly. I would love to hear from others with this similar problem and any insight they have on it.
