Eight percent of all Germans, Austrians, and Swiss suffer from depression, twice as many as those who have cancer. Nevertheless, the illness is hardly acknowledged publicly, as those who are not affected cannot understand it. The affected individuals, in turn, remain silent; they fear being labeled as mentally ill or do not even realize the extent of their condition. Roland Zingerle is one of those who does not stay silent. For years, he ignored the cries for help from his soul until his body finally gave out. In "Diary of a Depressed Person," he recounts his slide into depression, his therapy, and his arduous journey back. This book aims to raise awareness among those not affected about a topic that has long been at the center of our society, and it seeks to encourage those at risk to listen to their inner voice. Above all, it aims to help those who are affected.
