Our reactions to unhappiness can transform what might otherwise be a brief, passing sadness into persistent dissatisfaction and unhappiness. The problem with persistent and recurrent depression is not “getting sad” in the first place. Sadness is a natural mind-state, an inherent part of being human. It is neither realistic nor desirable to imagine that we can or should get rid of it. The problem is what happens next, immediately after the sadness comes. The problem is not the sadness itself, but how our minds react to the sadness.
