I've always found life experience and a certain kind of personality and mannerism is so much more important than qualifications for a psychologist, but I'm weird that way.

I was once forced to see a (fully qualified) psychologist in hospital. She was the same age as me, but actually had less education. She was . . . not helpful. Knew all kinds of textbook stuff, but nothing really about life. She seemed confused about why I speak in French to my father but English to my mother, which I don't really think was a tough thing to understand.
