I have just came across you post doing my own 'hearing voices' research. I am going through something very similar at this time. It's now been about three year for you. How are you? Did anything help? I hope so.
We are not alone, magedestiny. There is a great forum of people that hear voices exchanging ideas on the Internet. Here's the link:
My personal story, by the way, is there too, it's the one by Distressed Healer. I think you'll find much similarity. I too believe I have been attacked by dark entities, just as I was about to cross the threshold of significant spiritual awakening. I've now heard several, nearly identical, stories, of people being driven to hell from heavenly highs. Many recovered. I wish that for you too.
