You think you know what a person in psychosis looks like, but you probably don't. It's not confined to someone walking down the street screaming at hallucinations or ranting to everyone about the FBI implants. And it's not an axe murderer. It can be someone quietly sitting alone. It can be someone having an anxiety attack. It can be someone who's disoriented and dissociated. It can look like anything.
I've had psychotic episodes where I simply come across as depressed and a little confused. I've had them where I'm anxious and rocking and crying but I'm not loudly proclaiming my delusion.
I've had psychotic episodes where I thought my family was being stalked and I had to harm myself to appease the beings stalking us but nobody knew. My injuries were hidden and I simply stayed inside the house.
I've had voices make me feel terrible so I just cry and talk about what an awful person I am but that just looks like low self-esteem.
It can be right under your nose.
Stop acting like you know exactly what psychosis looks like - especially if you assume people who have it are violent and out of control. If someone tells you they have psychosis or schizophrenia, don't treat them like a ticking time-bombs waiting to kill someone.
