Thank you so much for posting this!
I have never heard this described so well and throughly. It answered a lot of my questions. I don't have alters but I have most of the rest of disassociation behaviors described. At 36, I have begun really dealing with the disassociation. I was always scared to tell anyone about it prior. I thought people would think me insane, lock me up, and throw away the key. Also they are really hard to put into words. I curl up inside my body and leave my brain stem behind to keep me functioning. because to many people they do sound crazy.
Now I have a therapist well versed in PTSD and sexual trauma survivors. I felt it was time to tell someone who might understand. She basically said it's a normal response to trauma. Time to start to working on it now. It's tough to leave behind though. It's a safety blanket I have been wrapped up in for decades.
