Struggling With Stopping

I'm at a very pivotal point in my life, ending one chapter of my life and moving onto the next. However, as far back as I can remember (around 15 years) in my youth, I've been a compulsive picker. At first, my parents didn't mind too much and I did it when I was bored, nervous, stressed, etc. They got divorced when I was still very young, which only exacerbated the problem. Fast forward eleven or so years, I'm still a very compulsive picker. I've expressed desire to my parents about seeing someone and even got a referral from a GP to try to get this worked out. After two months from the doctor's visit, I still haven't seen anyone about it after that, and the only steps is my parents saying to stop picking when they see me do it, which only causes me to pick more. I feel like at this point, I have to pick to stay sane and I don't know what to do anymore. Can anyone share their moment of wanting to quit and taking steps to get there?
