Adjusting one's insides is a lot tougher than changing one's outsides. A good post on psychotherapy: Change. One quote:
...why see a therapist? Because it is very difficult to see yourself clearly. Just as a camera cannot photograph itself except in reflection, the kinds of changes that are the heart of therapy need someone to serve as a mirror, as someone who can see and hear you without having an agenda about or for you, someone who can be caring and brutal. I can't think of anyone I know who has done that without help, including myself.
Therapy isn't about being happy, it's about honestly knowing who you are, and then picking a suitable life.
