Anger is not characteristic of bipolar disorder. Flying off the handle is characteristic of having uncontrolled anger, being ruled by your emotions. That can happen to anyone who has a bad temper, normal or bipolar.

If you're interested in learning about bipolar disorder, there are plenty of resources on the internet. Just ask Dr. Google. There are also checklists out there, self-help guides in case you think you or a loved one might have the disorder. If you look at one of those guides/questionnaires, you'll realize the only way to diagnose the disorder is to have intimate knowledge of a person's thought processes.

Best of luck with your client. If she's unable to control her anger, my suggestion would be to steer clear romantically. [emoji16]
