ktgirl, yes, my T shares about other clients, in a completely anonymous way. They are always examples that are directly relevant and have been helpful to me. For example, when I told my T about an adult male ego state I had been talking with, I felt so aberrant and weird. I was OK with myself having ego states who were younger versions of me, but an adult male I knew nothing about? I thought he would think I had gone off the deep end. But he shared stories about other clients and their ego states and I came to see how normal it was. Other times he has shared stories with my H and me about other couples and how they moved successfully through divorce. These examples inspire. I would love it if T shared a specific instance from my own situation with other clients and we have discussed this. I think this is really cool, because in this way I can help others, and also, I will "live on" for T even after I leave therapy, because he will be using my story with other clients. I love that part.
I think if you are uncomfortable hearing about other clients, you probably just need to mention it and your T will stop.
