Darkness in my head

We are all human beings, and we all have worries and problems. There is no person on the face of the earth who has not gone through times of despair and frustration, in which he hated himself, the world, and the people around him.
But we confuse depression as a disease with frustration, sadness, and distress. If you are frustrated by a difficult situation you have experienced, or sad about missing an important opportunity or losing a loved one, this does not necessarily mean that you are depressed.
Depression is a different matter, it has a different story, and sometimes it chooses certain people over others to attack, making them and those around them wonder: Is there a cure for depression? Can it be cured? How do we protect ourselves from getting it? How can we get out of any state of sadness or distress we go through?
You now have in your hands a book that will not only be useful for those who are depressed, but also for everyone who reads it.
