It is good you can recognize you are okay even if someone is frustrated or angry. I think talking to the therapist about whether she is those things or not might be useful. I am sorry if I missed it, but does she know about the chair and how it bothers you? I ask only because the one I see moves back away from the client to be less threatening. I myself would want the chair as far away from the therapist as possible so if there was a movable chair (the one I see has a stupid couch) - I would move it far away.
