"Rumination includes responses such as trying to figure out why you are depressed, crying to relieve tension, or talking to friends about your depression. It is known that rumination is likely to maintain or exacerbate depression, in part by interfering with instrumental behavior (i.e. taking action) and with effective interpersonal problem solving. Moreover, individuals who ruminate a great deal are more likely to develop full-blown major depressive episodes. Finally, self-focused rumination leads to increased recall of more negative autobiographical memories, thereby feeding a vicious circle of depression."
