Thank you everyone for your thoughts, sharing your experiences and your insight.
Things with The Other have gotten a little better since. She is apparently "freaked out" at the thought of there being more alters besides herself. She had no awareness of the rest of us until recently.
She has been talking to our psychiatrist and our T and has been receptive to their suggestions on what to do. She introduced herself in our journal and a few of us wrote back.
She has apologized for being insulting toward Angela, but she says she won't apologize for being herself. Fair enough.
I feel a little silly for writing for her so I will stop right here lol
