<human>: *Facts: I am a male, 19yrs. She's a female of 19yrs.*   
My girlfriend of +6 months recently flipped on me. I knew she had been diagnosed bipolar but the most I had seen of it was random mood swings where she would get kinda depressed for a few days.  
This Friday night she really freaked out, cutting herself and vocally degrading me. She was a totally different person, and I did not like it.  
She had calmed down by Saturday morning and apologized and explained to me that that was her worst side and it's normally under control because of medication.  
I am at a loss on what to do. I really do like her, but I'm not sure I can handle the fact that she could flip out like that again. Any help?

Can you condense the text into a few key points?
