Real life is different from a novella by Dickens, a short story by Stern, or a movie by Capra; in part because there’s not a writer or director making sure the intervention happens. Also, not everything gets tied up at the end. However, if you or someone you know is experiencing symptoms associated with SAD, it is important to take two big lessons from these fictional works: 1. You are not alone. 2. You can get help.
