Not sure why I do this but last few years are started picking at my hair, not pulling it out or anything  but just playing with it or picking strand by strand out of a pony tail. I get this weird....reliefe feeling, and I can't ever not be playing with my hair its just a constant urge. Does anyone else do this or know why people do it? I do have extremely bad anxiety so I figured it would be connected, just a weird thing to do
