In general, therapists are trained to be non-judgmental and understanding, so discussing past therapists during a session is usually not an issue. In fact, it can be quite helpful for the current therapist to understand your previous therapeutic experiences, as it provides valuable context for your current concerns and preferences.
However, it's essential to consider how and why you bring up the topic of past therapists. If you continuously compare your current therapist to past ones or express unrealistic expectations based on those experiences, it may cause some concern for the therapist. It's essential to maintain an open and constructive dialogue with your current therapist about how you feel in the therapy sessions.
If you are worried about discussing past therapists or any other topic with your current therapist, it might be helpful to share your concerns and feelings with them directly. A skilled therapist will be receptive to your feedback and can address any potential discomfort or annoyance in a professional manner, ensuring the therapeutic relationship remains productive and beneficial for you. Remember, therapy is a collaborative process, and open communication is key to its success.
