What are the common symptoms of bipolar II disorder?
During a depressive episode, you may notice persistent sadness, emptiness, hopelessness, low energy, difficulty concentrating, or loss of interest in things that usually matter to you. Sleep, appetite, motivation, work, relationships, and basic routines may also change. These experiences vary from person to person. What matters clinically is the combination, persistence, severity, and effect of symptoms, rather than whether every possible sign is present at once.
