And I'm the counter anecdotal case of your anecdotal case.

I have a page long list of failed psychiatric regimens that included drugs alone and drugs combined with talk therapy. None of them effective.

I won't say that I'm cured of depression now or will ever be. But a strict and persistent exercise routine lessened it to the point where I can function day to day. This was never achieved with presrciption drugs or therapy (of which I have developed a dim opinion).
