My understanding of the way therapy works is that if you have a psychological problem that you cannot solve on your own you hire a paid professional, you share your problems with him or her, he or she helps you understand how to solve your problems, and then you move on with your life and hopefully apply what you learned in therapy. The therapy itself should last only a few months. But then you have people who, by their own admission, have been working with the same therapist for as many as 3-15 years. I believe that keeping a person in therapy for so many years not only says a lot about the curative capacity of the professional but also suggests a lack of ethics on their part.
