I am really sorry this happened to you. It's a shame when the therapist can't handle negative feedback. Dealing with the feedback constructively is part of their job, and when it's handled properly it can be the most effective part of therapy. When the therapist terminates the client just because the client didn't like something they said and was honest about it, it's a shame. If they don't want to hear any criticism they should choose a different line of work. But, frankly, it's not even about being professional. Any adult should be able to handle criticism. Talking things out and getting to a point of mutual understanding is a part of any mature interactions.

Honestly, some therapists act like little babies! Just how insecure one should feel to end the good work with the client just because the client expressed some displeasure about certain things the therapist said! What were you supposed to do? To keep your feelings inside? Aren't you, as a client, encouraged to talk about how you feel? I am really sorry..
