I don't think dissociation is necessarily a bad thing, Lady Lindsey. As you say, this is a coping mechanism for you and as long as you recognise it as such it's a useful thing. And if you can put it aside when you need to work with your t then it's not as if you're being controlled by the voices - you are controlling them.
I'm so glad that you have a bit of relief - you sounded so desperate earlier.
