Schizonphrenic (?) friend. How to deal with it?

[charlize001]

For years we were just really good friends.  She was kind and complimentary though always somewhat self-absorbed.  Then wham, out of the blue, she became cruel and mean, pugilistic, seaming to want to turn anything into something to be offended by.  There were all of these accusations where I was being, well "...a cold-hearted ***** who doesn't care if you hurt me over and over again."  None of her accusations were seemingly based on any reality.  After this all began, at first, for a year it seemed, I let her vent, but finally I had enough and I told her that she was like two people, and that I just totally rejected all of her accusations.  I am still blown away by it all.  The two people thing got her angry (hurt), told me that it brought back to her conversations she had with her mother, how her mother said she always ruined good things.  She as talked about her "inner voices" and the bullying she received growing up.  She is very bright, but seems to identify as being a victim.  She goes through stages where she gets really angry with her friends and writes them off.  Then things can get back to normal for awhile.  Finally, after the two people thing, she volunteered that she has worried about maybe being schizophrenic.  That sent me scurrying to read up on schizophrenia.  It sounds right, explains a lot.  I now worry that I just really mishandled the whole situation, though I have no idea how I could have changed any of it.
1.  Does this sound like schizophrenic behavior?
2.  If she is an undiagnosed case, how do I deal with it?  That is, do I confront her when she is accusatory or not?
3.  Any other advice would be most welcomed

Thanks for the help.  She isn't on meds, and just is concerned about having symptoms and gets upset if it is even slightly suggested that she may be.  I'm not sure how to deal with that.  It seems odd to me that her parents, esp her mom, brought up the problem without seeking any kind of help for her.  Anyway.  Thanks again for your input.  I am going to assume she is, and that will help a lot in how to deal with it.  I've read that you shouldn't allow the accusations slide, to confront them.  Would you agree with that?
