everything, can you do a little accounting for yourself and evaluate where you you think you are right now to where you were 6 months ago, and how seeing this therapist has helped? Then ask the therapist the same question. “I was surprised by our email and it made me think. What do you feel I have accomplished in the past 6 months since I have been coming here?”
If you both recognize the same accomplishments then you are on the same page. If you are not on the same page then that is some you should be discussing.
