Pediatric bipolar disorder is commonly characterized by outbursts of anger, irritability and psychosis, rather than euphoric mania, which is more likely to be seen in adults. Early onset bipolar disorder is more likely to manifest as depression rather than mania or hypomania.
The classic symptoms of bipolar disorder are the periodic changes in mood, alternating between periods of elevated mood (mania or hypomania) and periods of depression. If you are living with bipolar disorder, you may feel energetic, abnormally happy, and make reckless decisions during manic states. During depressive states, you may feel the overwhelming urge to cry, experience feelings of hopelessness, and have a negative outlook on life.
