Well, I don't think this song is about personality disorder or mental illness. I think it's just about the common flaws everybody have. She says ''Everybody's got a dark side''. Well, not everyone is mentally ill! But everyone has some flaws. Like she said ''Nobody's a picture perfect.''! Everybody has their own flaws which they want to hide. They fear rejection from the ones they love due to those flaws.
