How do the theories of depression relate to learned helplessness?

The theory of learned helplessness means a condition of a human being or an animal in which it has learned to behave helplessly, even when the opportunity is restored for it to help itself by avoiding an unpleasant or harmful circumstance to which it has been subjected. One theory of the causes of depression is that depression could be caused by genetic traits, stressful events, illness, medications, or other factors, can lead to an imbalance of brain chemicals called neurotransmitters, causing depression. The theory of depression, the cognitive theory, is related to learn helplessness because, to begin with, they are both dealing with depression. Then, they are both caused because of something. For example, in the case of medications, if someone is fat and feels that the medications do not work they get all depressed and think that it is their fault and feel helpless. Both occasions are link because you get depressed by something and therefore feel helpless.
