As I set out to understand depression, and to interview people who had experienced it, I found that there were people who seemed, on the surface, to have what sounded like relatively mild depression who were nonetheless utterly disabled by it.
Då jag bestämt mig för att förstå depression och intervjuade personer som varit med om det, kom jag underfund med att det fanns personer som på ytan verkade ha en rätt så mild depression men som trots det var ytterst handikappade av den.
