well, it makes perfect sense that you would think people are out to get you, especially authority figures, when you are experiencing what is basically the ultimate creativity of the mind (which we happen to pathologize in this society) - and doctors & nurses, who are supposed to help - are denying your experience, telling you it's a disease. what choice does your mind have when faced with their ignorance and insanity? none, really, but to come up with even "crazier" explanations.
in the sense that you are not free to speak without judgement or potential harm to yourself (being medicated or institutionalized), they ARE out to get you. i am very sorry about where we are in our understanding of different levels of symbolic thinking, something "schizophrenics" are fantastic at, but alienated for, and made worse. just the fact that people look at you funny or don't appreciate your perception of the world will make anyone lose it.
