Lost,
Remember you are not alone, if nothing else, you always have the voices...I can relate with the obsessions, not the "literal" voices such as you are dealing with. I have "inner" voices that try to get me to harm myself, but mostly inner dialoge some would call a conscience, but mine seems to run at full speed and I can't seem to slow it down.
I find that when my depression and mania is not out of control then most of the time things are also quiet inwardly.
I do often have flashbacks and horrible images that invade my mind at times, and while faith isn't for everyone I find that my faith significantly helps me with these matters.
You and I have spoken about some things in the past, and perhaps we should speak of these things sometime, but I HIGHLY recommend that you read the book I suggested to you, and for others reading this post with similar feelings and thoughts, I have suggested a book by Author Jim Logan titled "Reclaiming Surrendered Ground".
Blessings to you Adrienne,
J
