Well my personal opinion about voices in my head is that I summed it down to three things, My voice, Gods voice and the enemies voice. My voice is what I hear bickering between the two. Gods voice is what is telling to do thing that are right for me and sometimes I don't understand why he wants me to do it but it laters reveals itself. Then the enemies voice who tries to convince me to do things that are harmful to me and my well-being. Sometimes I feel like I am going insane with the chaos that goes on in my head but sometimes I just take in a deep breath, relax and it all goes away.
Some may say I am insane but that is okay at least I got my voice pegged down. :]
