Hello MusicMan2016: Well... I read your post. But honestly I don't know what to tell you.

We here on PC are not in a position to diagnose people. From what you wrote, it sounds as though perhaps your friend is struggling with some sort of multiple personality disorder. But I obviously don't really have any idea.
In order for your friend to figure out what's going on, & what can be done about it, she needs to see a mental health professional... perhaps a psychiatrist as well as a mental health therapist (assuming she's not already doing so. Perhaps she is & you just weren't aware of it?) Assuming she's not, though, she needs to make the decision to do what is necessary to heal. Others cannot make that decision for her. Given what you wrote, it may be best for you to simply move on if you can.
I see this is your first post here on PC. So... welcome to PsychCentral… from the Skeezyks!

I hope you find the time you spend here to be of benefit.
PsychCentral is a great place to get information as well as support for mental health issues. There are many knowledgeable & caring members here. The more you post, & reply to other members’ posts, the more a part of the community you will become. Plus there are social groups you can join & chat rooms where you’ll be able to connect with other PC members in real time (once your first 5 posts have been reviewed & approved.) Lots of great stuff! So please keep posting!
