Can fiction books really help you feel better? Using books as therapy has actually been around since the ancient Greeks, it was used after World War l and World War ll to help returning soldiers deal with post-traumatic stress disorder, and is currently used in educational settings as therapy for school-aged children. While non-fiction, self-help books are commonly sought after by individuals looking for help dealing with a specific issue, fiction books are quickly becoming a source of therapy for these same concerns.
