Could I be falling in to trichotillomania?

So for a couple of weeks I've been noticing I pull my hair out a lot, but not from the scalp at the ends. Well, actually at the scalp sometimes. When I do It I feel relieved. But I could do this forever. It gets in the way of my focus during class. I just can't stop touching my hair. After 5-10 minutes I'll finally realize what I'm doing. I even plucked out hair during a test from being so nervous. Sorry If this sounds dramatic.
