It's entirely possible that your symptoms are simply the result of being very strung out on drugs at the moment. Also, getting schizophrenic as a child would be an extremely rare thing to happen. I'm not saying it's impossible, but it's an extremely rare condition to develop before the teen years. First things first, you should get off of the drugs on your own or with help from a professional. You might be surprised at how much that helps a lot of your symptoms.
