You're not alone.

Like you, I've had trich since an early age. In fact, I also had a bald spot and hardly any eyelashes or eyebrows when I was in 6th grade. I'm 45 now and, while I still have trich to some degree, it's much better than it was.

I find I pick more when I'm either anxious or bored. It's usually just the little hairs around my hairline and my eyebrows these days. I also cant seem to leave things like hangnails or anything on my skin alone, although I don't pick until it turns into a nasty sore.

I did find some help through behavior modification exercises I did on my own (too embarrassed to see a counselor for it). Anything small and picky seems to work to distract from the self-abuse. Beads have been my sanctuary. I've also found something like a couple of marbles or some birdseed in my pocket or somesuch seems to help as well.

Hope this helps.
