I have noticed that when I get really severe depressive symptoms they happen at night and can last several hours. This is the time of day when I slow down. I am not necessarily always consistently depressed. When I am at work for example, I am preoccupied and symptoms aren't as bad' most days anyway. I do fluctuate between irritable and suicidal sort of like rapid cycling but it can happen within a day and sometimes I get so irritable that this will trigger feelings of suicide just simply because I get tired of dealing with people. I am wondering if other people with bp2 are in a constant state of depression when they relapse or if they have it more intense then symptoms subside and then repeat?
