"understand the trials of both sufferers and those connected to them" - That pretty much sums up the book. Its a series of tales told by some guy who worked with the mentally ill. He wants the mentally healthy to appreciate mentally ill people, not be afraid of them, and accept them.
That's a noble cause, but it makes for a dull book and the book doesn't go beyond that attempt. I suffered from mental illness (psychosis, for lack of a more precise term, or lack of wanting to elaborate) for a short period a few years ago (Not to suggest that I'm fully recovered, I think mental illness will always be in effect, and a full 'relapse' is always a fear). I really wanted this comic book to be about the 'trips' that occur - I wouldn't mind writing a comic about my experiences.
Instead of something really fascinating, this is a book concerning an outsider writing about the external realities of people having mental illness symptoms (I wanted to simply write: 'with mental illness', or even better: 'the mentally ill', but I want to shy away from defining those people by their illness. They are not the illness, they just experience it.) - I'm a big fan of Erich Fromm, the psychologist, and how he always says mental illness is defined in relation to the norm, and is significant to the extent that it prevents the person from productive interactions with society (ie, having a job).
Anywho, I think that mental illness sufferers suffer because of how they are treated - to a great extent, but not completely - and this book suggest how the suffering can be reduced by us non-sufferers "understand[ing] the trials of both sufferers and those connected to them".
If you've read this far, you don't need to read this book - go read a real book on mental illness while wearing your empathetic boots.
