One of the most telltale symptoms of a depressive episode associated with bipolar disorder is an overwhelming feeling of sadness and hopelessness. Individuals can fall into a state of depression and may have noticeably different symptoms than those related to a manic episode (where individuals experience a heightened sense of happiness and euphoria). They suddenly become sluggish and don’t see a point in pursuing goals.
Another common symptom is a near-total loss of interest in activities the patient once enjoyed, including sexual activity. This is often in stark contrast to what happens during a manic episode, when patients tirelessly pursue their interests and may engage in compulsive, excessive sexual acts.
