This paper attempts to show how psychic change occurred in the therapy of an adolescent girl, Lisa. First, I focus on some ideas in psychoanalytic theory concerning psychic change: e.g. D. Stern’s concept of “implicit relational knowing”, surprise and the intersubjective relationship between analyst and patient. I will then briefly introduce Lisa and her parents and present material from sessions, pointing out moments when I think that psychic change occurred. Not only my point of view will be considered, Lisa will also describe her experiences of our work together and share her diary with us. Looking back at our work together. I believe that my “love” for Lisa contributed to the psychic change that evolved.
