The Depressive Realist

Depressive realism is the proposition that people with depression have a more accurate perception of reality, specifically that they are less affected by the positive illusions of illusory superiority, the illusion of control and optimism bias. It must be understood that this refers specifically to people with borderline or moderate depression — while normal people see things in too positive a light and severely depressed people see things in too negative a light, the "grey" area in between leads to the most accurate perceptions of reality.
