Admitting I pick my face compulsively

Hello everyone, I am a 50 year old woman and I am a compulsive face picker. At first (at 7 years old), I used to pluck out my eyelashes. Then, I used to bite my tongue. Now, I pick at my face. I use this to comfort myself when I am anxious or bored. It is is extremely shameful and I look a mess when I'm done. I'd like to get help for this. Does anyone have any advice or experience with this? I'd prefer not to use drugs, though I do use Clonipin to sleep. I'd prefer some sort of therapy or coping mechanism or book. What has worked for you? Thanks, Mar
