He wasn’t diagnosed with it yesterday... He’s had it for years. Drugs do not give you schizophrenia. Period!
Drugs can give you psychosis on a temporary basis... If it last longer then it’s schizophrenia and you would get it regardless of the drugs. He has plain old schizophrenia...
There is no end to that... Because it’s chronic, but it is treatable with drugs and he was probably prescribed drugs, but he likely wasn’t taking them. Lots of schizoids stop taking their drugs because they don’t like being doped up... They like feeling as crazy as they can be, apparently its more desirable for them because being crazy is ‘normal’ for them and they like feeling normal.
According to Grok. You can look it up yourself if you want.
