What do you think her real psychiatric illness was???

I watched this movie tonight and I wondered if anyone else noticed that she showed signs of more than "Clinical Depression" I think that she was bipolar with also borderline personality disorder. There were also some areas that paranoid schizophrenic where also appropriate. I think that the movie shows the confusion people have when they don't understand true psychiatric illness. Great movie!!! Any other psych majors out there that want to discuss???
