Nobody knows.
Depression being the result of chemical changes in the brain is a
theory. Maybe chemical changes produce depression. Maybe depression produces chemical changes. Maybe both of those things are true. Maybe neither is true. No one really has a firm handle on any of this. But lots of people have theories, and lots are really sure that this theory or that is true.
