New to the site and I pick my lips

Hi everyone, I am new to the site but I wanted to share my story and get some advice. I am 20 years old and have been picking for as long as I can remember. My estimated start is age 13. My problem started with chapped lips and grew from there. I have picked my lip to the point where I have split it really badly several times and bleed profusely on a regular basis. I now have a permanent cold-sore like appearance. My friends tease me by calling it "mouth herpes". The issue is so unsightly that several years ago, a new teacher at my highschool (who had previously been a drug counselor) asked me to stay after class and then asked me if I had any drug addictions or wanted to discuss my abusive relationship, because it looked like I had been punched. I told her, "I just have anxiety," and she told me to seek help. I never did. I've noticed that I pick my lip a lot while I am driving, or in deep thought. But I also pick when I am upset or anxious, which is a lot. I even seem to do it without realizing....my 4 year old daughter has noticed and will put her hands on her hip and say, "Stop doing that thing to your lip, mommy." An elderly volunteer at my work also said, "You would be a beautiful girl if you could stop that thing with your lips." My friends are constantly grossed out and exasperated by my habit, but I just can't seem to stop. Does anything help? Will it ever end? I only pick in one spot, so I don't think my problem is very severe, but my lip (even between bouts of picking) is bumpy and red and does not look like it will ever heal. I just want to be done with this. Thanks in advance.
