I have been compulsively picking my skin and nails since I was a small child. I remember picking off a nail for the first time when I was 3 or 4 when I was on a "family" roadtrip which always stressed me out because my parents fought and I felt trapped in the car. The picking relieved my anxiety and I've been doing it ever since. Now I also pull out my eyebrows. Is this a borderline symptom?
