When I found this on YouTube I thought I would give it a go. There were a few scenes which were a bit triggering but generally it was handled well. If you have a couple of hours up your sleeve and are interested, I recommend giving it a watch.
I found they dealt with the whole topic very well....although there is one mention of her being 'Dissassociative' instead of dissociative, which I always find frustrating.
Truddi refers to all her alters as the Troops. and gives a few brief explanations of their functions. I am glad as I was after a rough rundown of how here system worked.

But it has helped. I may disclose more later.
