I don't have anything helpful to add, but appreciate the responses that have been posted thus far. I used to do this (especially with acne, but often with scabs too) until I learned it was related to my OCD and then I stopped. That lasted for a few months, but about 2 weeks ago I started up again and fell into the "can't quit" mentality as the acne/scab just "needed to be gone". Right now, I only do it very mildly again.

It is hard for me to sometimes relate it back to having an anxiety base, as it has gone from anxiety to a habit (so I guess it's an anxious habit, haha).
