Hello minus1: I'm sorry you are struggling with this.

I struggle with similar voices. I practice a Buddhist technique referred to as "compassionate abiding". Here is a link to a nice mental health related description of the practice in case you interested:

May it be of benefit.
As the 11th century Buddhist Machig Labdrön said: "In other traditions demons are expelled externally. But in my tradition, demons are accepted with compassion."
