I guess I have the same thoughts. Why is this a good topic for group therapy? And have you discussed and processed it at length in individual therapy? It sounds like such an intensely personal and difficult topic that if it were me, it would require a lot of work in individual therapy before I could share it with group. (Plus, knowing me, it would stay in individual, as I am not sure a group is the right forum for intensely personal sharing. Just my preference.) I hope at least, that your T has given you what you need--support, acceptance, understanding, empathy?--in individual therapy regarding this topic.
