I came across an article on Io9 titled 10 Comics That Can Help You Understand Mental Illness by Lauren Davis. In the article, Davis writes:
Comics don't always have the best track record when it comes to portraying mental illness. In superhero stories, mental illness is often associated with violence and villainy. There are, however, other, often personal, comics that can open your eyes to real human experiences with mental disorders.
Just a heads up: many of these comics deal with self-harm, suicide, and other issues that can be triggering to some individuals.
The comic books mentioned in the above article written by Lauren Davis, sound like intriguing ones to read. I'm all for becoming more educated with regards to various mental health issues and how mental illness effects those who are coping/dealing with one on a daily basis.
