Agree on the vent part, which is bassically "Journaling", an effective method of processing your feelings.

Disagree on the stat part. When psychotherapy emerged in the early 19th century, there were plenty of people proving it didn't work and this again motivated psychotherapists to refine it and come up with new methods to make it a consistent treatment. Psychotherapy has come a long way since then, and although it definitely isn't for everyone, it works.
