Been picking my lips for YEARS! Need to stop.

Hi, I am a 24 year old female and I pick the skin off my lips ever since I can remember. I do it every day... I pick my lips so much and for so long the first joint on my middle finger tilts in permanently. I don't ever remember having smooth lips. I pick until I bleed and still continue to pick after that. I have noticed that my mother picks her lips as well but not nearly to the extent that I do. I need to stop this, but I have no idea where to begin. I try to stop when I catch myself picking but it is such a huge part of my life most of the time I don't even notice when I am doing it. If I am not picking then I am running my tongue over my lips feeling for spots to where I can pick. I realize that I am addicted to picking, I am constantly searching for the 'perfect pick' if you will. The pick where the skin that comes off is big and just glides off, no blood and no pain. I get such a satisfaction from that feeling I find myself always hoping for that feeling every time I pick and get a piece of skin. I can't do this anymore... I have to stop, I need to stop, I want to stop. It is taking a huge toll on my life and I can't stand it anymore. If anyone has any advice please reply. Thank you.
