I have very negative thoughts from anxiety/depression. I don't know that I'd call it a voice. It is more of an inner dialog that is ongoing in my mind. I tend to think of it in terms of the ego. I read the Power of Now by Eckhart Tolle some years ago. If I remember correctly, he talks about you have the self and the ego. Most people think that their ego as themselves. It is pretty deep stuff. Glad you're getting some relief. I took Seroquel a long time ago. I would have to ask does this voice feel like you or something/someone else?
