My brother has the illness. Every ounce of self-doubt I have, I worry is the beginning manifestation of Schizophrenia in my own mind. It's not a good place to be - that worry that every time you "hear voices", it's some sort of announcement about your own mental state? The worst for me is mishearing people, or muffled conversations, where I fill in the gaps with extremely negative content, causing a downwards spiral in emotion. I'm sure it's nothing, and I'm perfectly normal though.
