Understandable, I hate being the center of attention, even for a moment. It sounds like you'll be joined by other outpatients, yes? Does knowing that they might be thinking the same thing help? Even the doctor/therapist/leader of the meeting is probably feeling the same nerves. I know that doesn't always help me feel better, but sometimes it does. Knowing that other's are sharing the same worries. But it's cool that you're involved in some activity that will help you learn to deal with things a little better. I'm a little envious.

Good luck to you.
