Being overstressed most definitely can lead to depression, but one thing to keep in mind is that recent studies suggests that a significant proportion of the general population experience both positive and negative features of psychosis, which generate feelings of depression at various stages in their lives. These experiences do not meet the criteria for clinical depression, but this effect only inferred that feelings of depression are common among the general population, and it is not something to be alarmed about. Therefore, feelings of being depressed are more common than abnormal and they are not permanent. People who experience these feelings find better ways to manage their stress and deal with the life issues that can send them into clinical depression.
