Was Ingrid Bipolar?

I think about 30 minutes into this movie (I'm not even 50 mins in yet) I started to think she was showing classic signs of bipolar disorder. She is elated, depressed, impulsive, promiscuous, highly creative, extremely into herself, etc etc etc. Did anyone else think this is why her character is so unlikeable, because of the instability in her character? I don't even know if she would have been diagnosed with anything truly, she just rubs me the way that some bipolar people rub me at times. What does everyone else think? Is she likeable? Possibly a person with a psychological disorder?
