War is a fact that happens since a long time ago which have been affected negatively a lot of people during the history. Every time a war finishes, soldiers have been victims of mental and psychological illness caused by war. The consequences of the war are devastated and everybody knows, but what most part of the people never realizes is, that soldiers not only suffer during the battle but principally suffer much more after, and most part can develop serious psychic diseases. One of the ways to treat these serious diseases is writing as a therapy. “A veteran of the Iraq conflict recently explained how writing saved his life over the past year’s readjustment to civilian life, saying, “The phrase, “welcome home” makes no sense, because the battle never leaves me. Writing has given me power over the conflict that is now inside me every day. Because I write, people can read what military go through long after the media and everyone forgets.” What this former soldier says tells us is that the catastrophic effects of war are not thousands of miles away in the streets of Baghdad; they resonate with urgency in the minds of those who return to the US each day” (Cathy Malchiodi). In the World War II happened a specific attack in Pearl Harbor, when the Japaneses bombed that American base affecting all american japanese community that had to move out to live in concentration camp. One specific family that lived in a concentration camp had a daughter called Jeanne Wakatsuki Houston that wrote a book (Manzanar) about her history lived in the camp. She used this book as therapy, writing everything that she lived, and showing the world how was the life within the concentration camp. War always caused problems in the society, and also devastated countries, but specially soldiers and civilians. The consequences of the war are so big that people developing mental and psychological disease that sometimes is irreversible. On the other hand, soldiers discovered that writing about their experiences during the war helped them to fight against mental and psychological diseases causes by the war.
