Oh my goodness!!
It seems to me that some way or another this does need to be discussed.
I had an odd situation with my T - and it was only a few days after we had had a session where I felt like she was real, that I could trust her. I was doing some googling, came across her name, and being curious, looked - it was in some complaints section of an online newspaper website. Someone who was a disgruntled former client displeased about counsel she had given to him and his wife in the midst of an acrimonious divorce, involving a child, too - not to give many details....but the upshot was, he was making various accusations and talking about how corrupt she was. And I was like, OMG! What is the real story here?! Can I still trust her?! The guy sounded like a sort of a loser in the letters he was writing....but still, I had no way of knowing what to think, because I didn't know what the story was at all......
I struggled with the question of how to bring it up and I ask her.....I didn't right away. But then a session or two later, there was some kind of opening, and I said, you know, there was thing I found online.......and she explained as much of the story as she reasonably could, and thanked me for bringing it up, because it was/is the sort of thing that can really affect therapy, hinder trust. So it helped me that she was honest about the situation (without breaking other clients' confidentiality, of course) so that I could see that it was a difficult case she had handled the best she could....so being able to discuss it with her did help me and help keep my trust alive. She wasn't mad about me bringing it up; she was glad for the chance to defend herself, and impressed I actually did bring it up!
So.....this is something I would carefully consider asking for further clarification/explanation about, if it is indeed still bothering you after a few days or so!
