I did not find my therapist promises unprofessional. I took her promises literally, and expected her to keep them. She did. Once I figured out she wasn't going anywhere I looked for every reason why I should quit. I am not saying this was the op's situation at all. It was for me, and it worked out in our therapy. I am quite confident that I would be in a totally worse place, or at least the same place before I started therapy. I'm glad I went for a zip ride based on a promise. I don't think I would have gotten to a happy shore if I didn't. This is just how it worked out for me.
