How' s this: (and I am not kidding): Firestorm could write how everything makes her feel and then rip up that paper and burn it in a big pot outdoors while Destiny sings and dances around the fire, Little Princess gets held tight while you all go round and round, holding on, loving and laughing, and Bloopsy Rose can yell and not feel guilty and you can all cry together.
I burn things I write sometimes, giving up that energy to whatever/whoever and it has helped me a lot. I cry sometimes when I do it as well. If you do this, perhaps the parent will make sure everyone is safe. Maybe your therapist will help you to do this, or you could do this little ceremony in your head when you are alone. I used to imagine cutting a large chain between me and my ex with a loud chainsaw....funny, but I always felt better after.
