It's true, unless you have DID, you can't imagine how hard it is. Even if you read up all you can, you won't ever know what it feels like deep down. I have that argument w/ my T. She specializes in it but just doesn't understand some of the things I tell her. Hope we can answer some of your questions. May I ask why you are asking? Just outta curiousity, do you think you are DID, someone you know?
Love,
RM
