I don't know how you normally are in session, whether you can look at your T or not? I was asked to be an "example" for a Georgetown University Medical School psychiatry class where I sat up on the "stage" with the psychiatrist professor (whom I didn't know) and he asked me questions which I answered. The med students could come in or go out, etc. as they liked. Anyway, I remember I had a "rubber band" with me or a paperclip (???) and that was wonderful, having something to keep my hands occupied and to "focus" on. Maybe you might like to "hold" something or twiddle :-) with something like I did.
