My best friend used to do the same thing, she bit and bit until
they bled and were nubs. I, myself suffer from trichitilla?? I
pull out my hair. Done it as a kid too; eyebrows and eyelashes,
I looked retarded. I got made fun of and questioned why? never
knew the answers.. til Pc. needless to say, my bestie has nice,
healthy nails now... and I resume pulling. I guess it's OCD??
idk. Check out that page, it will def give u input and perspective.
Best Wishes
