Call it dysphoric mania, agitated depression, or a mixed state: nobody will understand anyway. Mania and depression at once mean the will to die and the motivation to make it happen. This is why mixed states are the most dangerous periods of mood disorders. Tearfulness and racing thoughts happen. So do agitation and guilt, fatigue and morbidity and dread. Walking late at night, trying to get murdered, happens. Trying to explain a bipolar mixed state is like trying to explain the Holy Trinity, three persons in one God: you just have to take it on faith when I tell you that the poles bend, cross, never snapping.
