New here, could use some guidance

I'm a 30 year old man in New York, and I've been picking since I was a kid. I remember passing hours ripping at my arms until they felt like they were on fire. My main areas of focus have been my arms and chest, though the face was always a part of the problem, in the last few months I've been focusing on my face with greater attention, namely my forehead, between my eyebrows and along them. I will stand at a mirror, leaning over the sink with my arms on either side of the mirror while spending long periods of time working the skin on my face. I'll stand there until my knees hurt, until my back and shoulders hurt. I'll pass over the skin once or twice, then aggressively moisturize my skin, thinking that it will prevent any marks or scars in the long run. I've started using neosporin to help things heal faster, I've used SkinFood to help cool the puffy red aftermath and speed up healing, I've used Proactiv, hoping it will clean up the pores I have been picking at for so long. I try to compromise, saying that this time, no nails, just push hard with the fingers or, or placing my thumbs next to each other and rolling the skin up between them, pinching and bruising. I've seriously considered microdermabrasion treatment to help with my very uneven skin, hoping it will even the ridges out and make the damage less visible. I have a problem where I often find myself picking just before leaving the house, then I see what I've done and treat it with moisturizer and visine to take the redness down. I've been spraying my face with cooling thermal spring water, and researching anything that may finally make it so I have nothing to pick at - though I'll always find something. At night in the dark as I'm falling asleep, I trace my fingers over my back feeling for any bump, or the back of my neck, or my scalp. Most times I feel like I catch myself doing it, like I disconnect and just start ripping at myself, there are times when I plead for myself to stop, but it continues anyway... I need to find a way to deal with this. At this point, I now have soft, fleshy and sensitive nodules on my forehead where I've been unable to stop myself from picking, I hope they go away. Any advice, and information, any help is appreciated - I have been able to quit smoking, but this I just can't seem to do.
