Well, I'm not too positive on how accurate the bipolar quiz is. Just be sure not to diagnose yourself based on an online test! If you're concerned about your result though, you should see a psychiatrist.

I took the bipolar quiz out of curiosity and received a 23 (Either a mild bipolar disorder (II) or depressive disorder). Personally, some of my answers to those questions on the quiz came from the way I act out of my OCD. So other disorders can have similar characteristics, which is something to keep in mind.
