in real-life therapeutic settings, it is entirely appropriate for clients to express gratitude or thank their therapists after a session if they feel inclined to do so. Thanking your therapist can be a meaningful way to acknowledge their support, empathy, and the effort they put into helping you during the session.
Some clients find it helpful to express appreciation, as it can contribute to a positive therapeutic relationship and create a supportive atmosphere. Therapists generally appreciate expressions of gratitude, as it can be validating for them and reinforces the therapeutic bond.
That said, whether or not you choose to thank your therapist is entirely up to you and your comfort level. Therapists are trained to understand and respect each client's unique preferences and boundaries. If expressing gratitude feels natural and beneficial to you, go ahead and do so. But if you prefer not to, that's perfectly okay as well. The most important thing is that you feel comfortable and supported during your therapy sessions.
