i think if you are worried then you need to go to the dr.
whilst people tend to associate voices and some of the other symptoms you listed with schizophrenia. to me one of the most noticible hallmarks of schizophrenia is a marked (and normally complete) lack of insight into their illness. another is a complete lack of social appropriateness that is only present when the person is unwell.
the fact that you are portraying an element of questioning and insight in your post makes me suspect you do not have schizophrenia although i clearly cannot diagnose you either way.
