Hello Katix3,

I'm sorry you are going through this. I think you may find that you get more responses in this forum, as it deals with those who have multiple personalities, or "alters":

It is a common misconception that schizophrenia means multiple personalities, it's actually called Dissociative Identity Disorder now.

I would encourage your friend to get some help.
