That's hard to hear, so I understand your upset over what she said. I think it's okay for a T to be unsure of which step to take forward, but they need to be looking for next steps and feel hopeful about change, even when their client does not.

I think you should share how painful it was to hear her comment, and perhaps you and T can discuss what to do next. Can she try a different approach? Or recommend another T who has a different skill set?
