The main book which covers mental illnesses is the Diagnostic Statistical Manual/ DSM. Try #362.20-362-26 or RA790.7 at the library for stories about how to deal with mental illness. The mental health section goes from #616.85-616.89 and RC435 to RC515 at the library. Remember that a hundred years ago or so, no clearly defined mental illnesses existed now they got thick books with all kinds of specific mental illnesses but I don't buy it. You are who you are, a unitary whole. You might feel depressed in the morning, grandiose in the afternoon then histrionic at night. At best, these so-called illnesses are a rough guide to what you're going through. You're you. No other human being will ever know what you're thinking. No label can describe your unique set of circumstances and feelings otherwise known as your life yet we got an entire industry of phony experts pretending they know something deep and advanced about the human condition.
