Yes, your T can help you work on transference with others in your life too. Transference is all around us, and a lot of what therapy deals with is figuring out how we are affected by that. Since you can have them talk to each other, your T can get both sides of the picture, and that should help even more. And you can also talk to your psychiatrist about your transference with him, even if he doesn't do therapy. He is part of your therapy team, even if he mostly manages your meds. You must talk to him enough to develop this transference.
