well... when i was about 9-ish in therapy i would pull chunks of my hair out when i needed to say something but couldnt get my mouth to cooperate. :/ ive also dug into the palms of my hands before, for the same reason. its not really intentional, and i dont really know the reasons why exactly. quite a few of those times i would need bandaids afterwards. and i usually wont notice it until some form of pain kicks in over it.
the hair thing stopped after my T would create options for me to point at on the white board. but then if there wasnt an option that she wrote up that i wanted or was trying to communicate i would start stressing out over it big time, quickly going into grabbing my hair... then screaming when i couldnt get the hair untangled from my hands... and the wall was actually climbable (lol sorry that had no releveance at all, but i loved that wall and this is one of the rooms my T would take me into.
