Skin picking disorder? (Possible tw)

So I’m 15 and I have been professionally diagnosed with pretty bad anxiety, adhd, depression, and a handful of other disorders. I know those disorders can cause people to form nervous habits or hurt themselves but this seems different? Every day I spend at least an hour in front of the mirror picking at little imperfections in my face and back (mainly acne) and sometimes I’ll spend hours pulling out leg hair with tweezers. This is my face after a particularly stressful day:

Not exactly pretty lol. I wanna stop but have been finding it hard to so I figured I’d post on here and see if anyone had some insight. I don’t wanna self diagnose as I have no idea what the hell is going on but I looked it up and it might be skin picking disorder? I don’t know. But any tips on what to do to control it or what it could be would be greatly appreciated 🧡
