Does this happen to you to? When I have something in my hands (pencils, pens, cutlery, towels, etc.) I begin to subconciously chew or bite it; and when I don't have something in my hands, I start biting my fingers. It gets worse when I have rage outbursts, because I even bite pillows, notebooks, and symilar things. I tried to stop it, but I couldn't.
Is there any way to stop it?
