St. Joan of Arc heard "voices" in her head. Is that what you're referring to?
I don't know her biography all that well, so I don't know the answer to your question.
However, this article speaks of that negative voice that always makes us anxious, angry, bitter, and so on. That little devil that most people with depression and anxiety deal with, the one that always tells you that you are going fail, aren't good enough, unloved, etc.
Please, do read the whole article. It only takes a few minutes. I just want to see if anyone here has anything to add to this or have any particular thoughts.
This is a religious treating of the subject.
