One can withdraw, without ever leaving the room. It could undermine therapy, if you let it. Then again, it can reinforce therapy, when you recognize it, for what it is. Of course, screaming elevates the stress reaction, for sure. Places one into fight/flight mode, it's physiological. Deep breathe, with eyes shut one moment, place self in at attention posture, then ride it out, if leaving isn't an option. Control facial expressions, as to not send antagonistic display. Remember, it's them being out of control.
