This is where you feel the need to pull your hair out. It is sort of related to anxiety.
I pull my hair out rather it is on my arms, legs or head. When I was younger I used to pull out my eye lashes and eyebrow hairs. I wanted to stop but I could not stop it at all.

So in 6th grade I had a bald spot on my head. It was totally embarrassing for me. I also had no eye lashes or eye brows because I have pulled them all out. now I do it less because I avoid mirrors. But it is hard still for me to stop because I am 24 year old and I am still doing it
I have my eye lashes and eye brows back So that is some progress
