I have been in therapy for 9 years, and while I have never left a session feeling like that particular session was extremely helpful, I have progressed SO MUCH over the past years, and if I look back over any several month period I can see how much my therapist has helped me. I'm far from perfect and I have a long way to go but I have made huge progress and it's largely do to therapy and my therapist, so I would say I count as a success story.
