What can I do about my midlife crisis?

I have provided a link below. It covers the psychology of Carl Jung, who believed that midlife crisis (the darkness of midlife) is caused by a psychological event where consciousness is overrun by unconscious contents. The site goes into great detail on how and why the midlife crisis happens. The site also contains a lot of alchemical symbols. This is because Jung believed that the medieval alchemists were themselves struggling with midlife crisis.
