Wow! I'm new to this app and was scrolling through the various groups and about died when I saw this group title. I've been struggling with dermatophagia since I was about 11 years old. I'm now 24 and still pick at my fingers and bite the skin off of my fingers. I have no idea why I do this, other than my mom did it and so did my grandma (what a thing to run in the family, right?). My hands are a wreck and scarred but hey, it could always be worse.
