'There are many things I don't understand, but here is one thing that I know. There is no such thing as the correct diagnosis. There are only symptoms, and catchphrases for various collections of symptoms. Schizophrenia, Schizoaffective, Bipolar I, Bipolar II, major depression, psychotic depression, obsessive compulsive, and on, and on. The labels mean nothing, because no two cases are ever exactly alike. Everyone presents differently, and responds to meds differently and no prognosis can truly be predicted. We are, however, creatures of containment. We want all things in life packed into boxes that we can label. But just because we have the ability to label it, doesn't mean we really know what's in the box. It's kind of like religion. It gives us comfort to believe we have defined something that is, by its very nature, indefinable.
As to whether or not we've gotten it right, well, it's all a matter of faith.'
