Oof. Her comment about Lizzo was way out of line. Lizzo (and everyone!) has a right to exist and inhabit their bodies and take up space.

Her comments about you giving off anxious energy and the impact on your clients might have some merit in it, but that is beside the point. She is not taking into account that it's WAY different being a therapist than a client and more importantly, that it's not her place to be talking to you about that. As your therapist, she is not in an evaluative role of your performance as a (future) therapist. That is for your professors and supervisors to consider and work with you of it's even an issue. She needs to stay in her lane.
