Crazy is a monster of the mind that drives us to harm. It usually drives someone to harm others, but on occasion it has been known to only harm oneself. Still, crazy drives us to harm.
As it harms, it zooms in on one victim—obsessing over only one person or group, usually under the self-delusion that it can somehow help. And, to everyone else, the victim is a liar.
When crazy comes after you, everyone will tell you you’re wrong, you need counseling, or you see ghosts. Take heed; it’s only a matter of time before crazy moves on.
