I've been suffering from this for about 5 years now, and I too just found out it was an actual psychological disorder. I have to say, it's nice knowing I'm not the only one going through this. I've tried just about everything at this point; telling myself I'm going to quit, fake nails, no nails. Gloves, long sleeves, therapy.. Everything. The only thing that seemed to work the best was clipping my nails very short, but being a woman who values her appearance, that's pretty much a no go. What all have you tried ?
