Insane is probably not a useful word in this context. Is it possible that you are suffering from an illness? Of course it is. The internet is not the place to seek a diagnosis. Make an appointment with your primary care provider or a qualified mental health professional. There are a number of illnesses that can manifest themselves in ways archaically referred to as mental. Just keep in mind that everything that happens in your brain is chemical and electrical. If you are having a psychotic break, and believe me I do not mean that as a pejorative but simply as a medical term then you need qualified medical care. When asked, a schizophrenic patient will say when they began to hear voices they were as real to them as their friend talking from the next room. I wish you the best of luck. Get help. If you need treatment, get healthy. These are tough issues. Hang in there.
