mental illness is not genjutsu , you are an *******. making fun of people wit mental illness. genjutsu techniques manipulate the flow of chakra in the victim's brain, thus causing a disruption in their senses. someone has to cast genjutsu on someone. Fail Thread
schizophrenia doesn't make you hallucinate seeing demons everyday. It's more of an auditory hallucination rather than a visual one(hearing voices). Even if it were a visual it would be more closer to paranoia, thinking you saw something when you didn't rather than clearly seeing something such as a dragon.
Please, stop conflating things. Genjutsu is an affliction CAST by somebody onto someone else. Unless there is someone who can directly cause another person to have schizophrenia, schizophrenia is NOT a genjutsu. Do you want the two definitions to be laid out, compared and analysed to demonstrate just how wrong what you're saying is?
