I've heard of that.... so far it's been me against them. I don't even like phrasing it that way. Or them against me. It's not nice, fair, or equal. It's not respectful. It's like:
(me)"You must obey ME because I have to obey the world."
(them)"OR - YOU obey US because WE don't like what you say and can ruin everything for you."
(me)"Why would you possibly want that? What good can it possibly bring you?"
(them)"It makes you suffer."

why would they want me to suffer???
I know I have to ask these questions of them (and I do, and I either get cheeky answers or they all walk off or they engage in unhealthy behaviors), but we have bills to pay, a roof over our head to keep, food on the table to get... I don't see why this is even a question.
Well.... I do sort of know.... all tied to the programming of the past. damn the past anyway.

But for this biting issue, we're working on creating a new identity for herself which I think will be good. Then I need some willing test subjects (family to put their arm within reach at random times to untrigger that desire to lash out. It wouldn't be the first time she's changed animal identities... snake...cat... wolf... so now we're looking at thunder storm (something still powerful but WITHOUT fangs!) and tie that into a liked book character. This might just work. Go imagination, go!!!
