Prayer for a Friend

[Mayflower1]

A friend of mine has undiagnosed dissociation. I am not a doctor but she goes for hours or a day or so at a time and not remember it. Her counterpart has a name and has talked to me on several occasions and said "I will die a horrible death." talking about me. My friend said that her counterpart hates me and said she would kill me if she could, but didn't want to get my friend herself in trouble so couldn't. I consider it an empty threat, but this really concerns me because she is my best friend. I know I can't hang out with her alone, at least not until she got help, but I was thinking that I might tell her I was going to call the police if she didn't let me take her to the hospital. I'm not sure if that is a good idea or not but I feel like I have to do something. I have counterparts in me but they don't come out like my friend's. I imprisoned one in one part of my mind, and the little girl in my mind, I at first tried making a grave for, but sort of had a rebirth where she isn't a scared, frightened little girl anymore. I role-play a lot and had abuse in my past so that is where it comes from and that is why I can relate to my friend so much and forgive her, just want her to get the help she needs. I don't want to call the police because I live in a small town and word gets around fast. I don't want to do that to her. But I'm unsure what to do so would appreciate prayers.
