The correct answer is Bipolar Disorder
In bipolar disorder, people alternate between periods of very good mood (mania) and periods of irritation or depression. So-called "mood swings" can be very fast and occur very often or infrequently.
During a manic episode, a person with bipolar disorder can manifest both euphoria and irritability. Many people with bipolar disorder 1 spend long periods without symptoms between episodes of the disease. Some people may experience rapid symptoms of mania and depression.
