Agreed about the no breach if names or details aren't use. At my T's office, they have a clinical meeting once a week, where they discuss difficult cases or things they have questions about with the other therapists in the office. But they don't mention names or specifics, so it's OK in terms of confidentiality. Though in this case, presumably the other T knew that your T was talking about you? Still, if all he said was that he felt uncomfortable (without revealing exactly what you said in session), probably not a breach. But I certainly understand your feelings of betrayal.
