Schizophrenia and God

I have a problem being a believer in God and a Christian and being schizophrenic. In certain Christianity, there is the belief in the voice of God, and the small still voice of Him. So, I try to seek after this voice of God, but the problem is not only is it hard to hear it, in the past without my meds I used to be tricked thinking that looking into a lightbulb and hearing my own thoughts or the schizophrenic thoughts was hearing the voice of God. You might say, forget about the voice of God. But, how can I forget trying to hear the voice of God, while being a believer?
