I never liked group therapy... and still don't like it unless it includes one on one with the same therapist(s) during the same week.

Try and keep to statements that portray how you are feeling, how you see what someone else is saying or doing... if you phrase it correctly, then no one can legitimately argue with what you are sensing.

What I get from that statement is.... how that idea affects me is.... When I hear something like that I...

Group therapy is definitely a time to use "I" statements, and allow the T's to help the others along.
