It seems like everyone is being very defensive of how the group reacted, but Imapatient, I think I see things like you do.

May I ask, how long have you been part of the group?
I know when I have participated in group therapy, I have always tried to be very supportive and sympathetic. If someone has the courage to disclose something deeply personal and/or painful, I respect that and honor it by responding appropriately.

From what you describe, it sounds like the group handled it badly. And the T handled it badly as well - maybe people were uncomfortable responding, but the T should have facilitated the interaction better, so that you could get some useful or validating feedback.

I don't blame you for not wanting to go back. I don't see how it could be helpful for you to take risks like that and be 'hung out to dry' afterwards.
I'm sorry it happened this way, Imapatient.
