I would say that it's possible that she felt uncomfortable about the personal tone of the email. It is possible that she wasn't comfortable being addressed in such an honest manner about how you felt (ironically enough, for a therapist). In other words, she may have wished that you had been more "professional" about the email rather than personal. While this wish is perfectly accurate and acceptable to most every other profession, I think therapists should be open to being addressed in an emotionally direct manner. Also, if I had to hazard a guess, I'd say that therapists do often suffer from "ivory tower syndrome" in that they are the ones doling out support and advice so often that they sometimes forget that they are fallible or vulnerable to making a mistake. A truly great practitioner finds the balance between the supportive, knowledgable therapist, and the perfectly flawed human being.
