you don't have answer this ... but in your reaction to what you've heard about your therapist, do you direct these same thoughts and feelings toward yourself? My sense is that they may say more about how you feel about you than her. This may be exactly where you need your therapy to go...to work through these feeling... esp with a therapist who may have been there. Maybe look at this as an opportunity to grow and learn.
plus, if you don't discuss it, this is going to be in the way of anything therapeutic you try to do with her.
