Sometimes these days I think I am schizophrenic
That is a serious condition.Why do you believe you're a schizophrenic?
I, for example, had fifty voices talking to me at the same time. I've heard them for years
While its good to be aware of any issues you might have, you should seek a proper trained professional in order to diagnose you correctly. That way you can get the help you need in order to get a handle on your mental health.
I'm not a nut case. I just want to get myself tested. My mates says I'm fine.
Just because your friends think you're okay, doesn't mean you really are. Only you can fully assess your inner feelings, and if you're hearing that many voices, I really believe it's best to get checked out. Getting treatment early is essential to a health prognosis.
