Today is World Bipolar Day. Also known as manic-depressive illness, bipolar disorder is a psychological condition in which mood, energy, and activity levels change dramatically, making it difficult for people to live their day-to-day lives. If left untreated, it can be disabling. As an individual with this disorder, I know the value of treatment in the form of medications and counseling.
