You might want to meet with your psychologist again a couple of weeks or a month after psychotherapy ends just to report how you’re doing. If all is well, you can wrap things up at that follow-up session.
And don’t think of psychotherapy as having a beginning, middle and end. You can solve one problem, then face a new situation in your life and feel the skills you learned during your last course of treatment need a little tweaking. Just contact your psychologist again. After all, he or she already knows your story.
