These are common statements made by depressed people . One major cause of depression is the stress caused by certain events in a person's life. Loss of a loved one, loss of a job, poor grades, family problems, financial difficulties, relationship problems, prolonged physical illness or other severe stresses are all potential causes of depression.
Depression can also occur when a person is attempting to deal with unpleasant childhood memories.
Although these factors may contribute to the onset of depression, research has not yet helped us to understand why a certain sequence of events will cause depression in one person but not in another. Individuals with certain personaility traits can also be particularly vulnerable to depression. Individuals who are self-critical and demanding are likely victims of depression. Those who tend toward perfectionism often become depressed when they fail to measure up to their extremely high standards. In addition, those who are passive and dependent in relationships are prone to depression when these relationships don't meet their needs, as they feel powerless to change or leave the relationship.
