Kazza, I'm not sure therapist get upset their treatment isn't working. That sounds a little immature. I am introvert either because that is my natural setting or because of the abuse I suffered. But my therapist accepts everything about me, it's not for her to not accept. Therapy as she says is more about my inner world than my outer world. Some people spend their life socialising and are no nearer to knowing who they themselves are, others like me use therapy to learn about me.
