If you are insane, you wouldn't know it at all. All schizophrenics believe that there is nothing wrong with them, it is the other person that is “crazy”. Incase you have used hallucinogens in the past, you were for that small amount of time. But other than that short term psychosis, it would be best to consult a physician to distinguish if you are labeled "insane". But if this thread is just to pretty much shoot the shit, don’t take my comment to seriously ….
