Tom Petty has announced that he will be releasing a biography, and that it will detail personal aspects of his life that he has not addressed publicly, such as his heroin use. I don't know, but I would imagine that speaking about these matters was very therapeutic--such things often are. Though speaking with an interviewer is not psychotherapy, I would imagine the end result might be similar. He likely gained a perspective on the events as well as received an emotional boost from the biographer, who is very open that he is a fan of Petty's work. The difference between this and psychotherapy, however, is that a good psychotherapist can often alter your perception of your story both by active listening and in re-telling the story back to you in a slightly different way. This can, perhaps, emphasize your personal achievement highlight certain successes. Kudos to Petty for his apparent honesty.
