Hi,
Psychiatric illnesses are usually approached in different ways. One way is to watch for signs and symptoms and compare with the diagnostic data available. Another way is to watch for responses to external conditions and people. Physical examination, obtaining information from other sources, rating scales, mental status examination, psychosocial history, cognitive tests all helps in diagnosing a condition. There is nothing wrong in watching and waiting before marking a person as psychotic as every individual undergoes some type of psychological trauma at some point of time in their lives. Develop positive attitude. You need not think you are getting isolated from normal people as every individual is different from others. Modern psychiatrists are assuming the role of leaders than physicians who believe in talk therapy than medical therapy. Please follow your physician's instructions and do not miss followup visits if warranted. Good luck.
