The MMPI-2 is a tool to determine where a person is emotionally - at this very moment. Unfortunately, at 567 questions, it's not like you can answer them every session. Personally, I don't have a lot of faith in the MMPI-2 for this reason. Typically, and in my opinion, those who use the MMPI-2 for evaluation purposes tend to place too much stock in the results.

Have you considered seeing someone else? Perhaps not immediately, but express your concerns to your therapist, and if you don't feel that your concerns are being addressed seriously enough, find someone else.
