I personally haven't seen it (so I'm sure it's no help). But I did hear she does decent job at portraying it. Not great. But decent. I did hear that Bradley Cooper did a better job in Silver Linings Playbook.

However, coming from someone who has seen Silver Linings about 50 times since it was released, I do have to say that even that portrayal is a bit off... but that's just me. The female lead in the movie seems more accurate to Bipolar. The more I watch it the more I think Bradley Cooper's character is more BPD than Bipolar. Still a good movie.

Off topic. Sorry... I'll stop now.
