Have you seen A Beautiful Mind? He had no clue he was going crazy. If you think you're going crazy, you're not. Do you have hallucinations? To the best of my knowledge, there's no pre-schizophrenia state, so it's very doubtful that you are in that state, and if you don't have full-blown schizophrenia, you probably never will. Also, it usually develops between the ages of 18 and 23--are you in that age range? If not, I wouldn't stress it at all (but I know you probably will, cuz i know how it is...)
