I don't know a whole lot about Psychotic Disorders. I'm aware of conditions like schizophrenia, but I don't think everyone is psychotic because of it. But what kind of disorders are there under the umbrella of psychotic disorders?
I believe suffering from addictions is a kind of disorder. Addictions occur when your reward system gets disrupted. This is a psychotic condition and a mental disease, according to me. Apart from that, OCD is also one of the worst mental disorder.
