OCD Diagnosis Confirmed?

Yesterday's Toronto Star had a front page article on nail-biting as a type of OCD. Seems I was more correct than I thought when I jokingly had my suspicions in an earlier post. Of course there is a range of nail-biting severity, but I think that I am pretty close to or (more likely) included in the OCD group. Just like the OCD-diagnosed individual mentioned in the article, I bite my nails, as well as the skin, which quite often leads to bleeding. Also, it has been an ongoing habit since as far back as I can really remember. Sometimes I am able to refrain from biting for a few months at a time (during which period I celebrate by painting them regularly), but the escape from the "habit" has only ever lasted that long at the most. Other symptoms they mention are superstitious or magical beliefs (sound familiar?) and tapping. As I might have mentioned before, I sometimes tend to type out lines of dialogue as I'm watching movies. Furthermore, I do other strange things like try to have an even number of steps between sidewalk slabs and parking spot lines. This last set of counting symptoms I never really took seriously because it just seemed like a childish habit that I couldn't kick. But in the context of these other "OCD-like" symptoms, I guess it might mean something a little more than that. Anyway, the name of this condition is onychophagia. Pretty awesome name, I must say. I wonder if this self-diagnosis means I need psychiatric attention of any kind? Weirdly enough, these possibilities don't frighten me in the least; they rather excite me.
