I would not wait to talk to your T just in case she already responds to your friend. I can't imagine that she would take her on, given your friendship, but just in case I would call and say 'Hey, T, you know 'Jessica' whom I've talked about before? Well she wants to begin therapy, and she wants to see YOU! I assume you would not accept her, given that I, your current patient, am good friends with her, but just in case I wanted to let you know that I would not be comfortable with that arrangement.'

I honestly don't think she would take this girl on. My T wouldn't even take my husband on, and he had been seeing us as a couples therapist to begin with so he already had a relationship with my husband. When my husband left the marriage he left couples counseling with our T, but I stayed and began individual sessions. Months later I expressed a concern that if my husband ever wanted to come back and start his own individual sessions with our T that he would take him and I wouldn't like that. My T immediately made a face and said there's no way he'd ever take my husband back, not now, it was far too late, he was 'my' T only. Just to be extra safe I told my T if he did anyway, I would never come back. Your T owes her loyalty to you, not some possible future patient. I'm sure she can find plenty of new patients, she doesn't need your friend.
