Dermatillomania

I have a horrible thing called dermatillomania. I overuse products, I pick at my face, I look in the mirror way too often, and I completely obsess over my skin. On a day to day basis I feel horrible about who I've become. I am so sick and tired of waking up every morning feeling sorry for myself because of the hours I spend in the mirror the night before. 
 
I have become so numb to the pain of my addiction  I just want to wake up happy. For once, I want to wake up and see the sunlight without having to feel embarrassed by the results of obsessing over my skin the night before. I am so ashamed that my mind, body, and soul do not have the strength to overcome this sickness. I feel so helpless that this monster inside of me has attacked my life for over a year now. God help me, because I can't help myself with the illness of dermatillomania.
 
I have tried numerous amount of options. I do not get acne and my skin is so great, but I destroy it because I try way too hard to be perfect. It's a cycle I cannot break. I will overuse products and irritate my skin, then I see the irritation, and I pick. I'll pick at it until it bleeds, then when scabs appear, I'll pick at it some more. 
 
I know the consequences of me picking, but WHY CAN'T I STOP? Why can't I overcome this habit of obsessing over my skin? I am so helpless at this point.
