The psychotic disorders can occur to anyone. There are various reasons behind the occurrence of the psychotic disorder. But whenever you see any psychotic disorder in anyone close to you, you need to know how to deal with that thing. Some people suffering from hallucination due to over dose of drugs may suffer from psychotic disorder. Also when a person is not able to overcome some sudden shock or some incident which has moved him from inside then also he may become psycho.
The very first thing you have to keep in mind that persons suffering from these things are not in their normal conditions and so you should always try and mix with them as someone who is the same state as they are. If you can mix with them as a friend and understand what they are exactly going through, then it will not be a problem for you to take them out of that particular situation. You have to deal with these persons very gently. Any harsh step may prove to be fatal.
