My brother (Bipolar, marijuana addiction) is going to see my therapist, who I've been seeing for about 10 months, for his sessions starting Tuesday. I feel great that my brother will give psychotherapy another shot with a therapist who already knows about our household, from my perspective, and I am happy for him. I also feel that she will get to know more about our household and might be able to help us better. But I also have concerns regarding the new material that will come onto the table and the impact of those conversations on her opinion of my brother and of me in both of our conversations.

1) Should we see the same therapist? Is it a good idea?
2) Have you ever had a similar experience where you and a family member were seeing the same therapist? How did it turn out?
