I think you should tell the female T that you have other issues besides the breasts that you would like to work on and ask if she can provide therapy for those things too, or does she just do body issues? (You don't need to go into great detail about what the other things are at this stage, I would think, just general, like "relationship issues", or "grief", etc.) If she only provides therapy for body issues, perhaps go to her for a few sessions to work on that and then transition to someone else who has a broader practice.

In any case, you will know a lot more about what you want to do after you visit both of these Ts. Good luck.
