My therapist doesn't express disappointment because that would be passing a judgment on me, and that's not her job or her place as my therapist. BUT, my therapist is human, and I'm quite sure I've disappointed her before, even if she did not show it. She gives me coping skills and resources and everything she can, yet I still choose to make bad decisions that plunge me into a deeper depression. I'd imagine that's disappointing to her to watch me ignore her advice only to harm myself.
