Well, unfortunately, I don't know much about this topic.

However, the explanation you provided does sound very convincing. I mean, it doesn't hurt to try, does it? Why not? After all, it'd be a far less painful and emotionally impacting way to deal with having the voices go away and such.

In the end, it's your choice whether or not to suggest it to her. But from what you said, it's a possibility and hey, who knows, it might help!

Either way, I hope things work out. Have a wonderful day!
