Are You Depressed, Or Just Human?

Depression can be devastating. Its worst form, major depressive disorder, is marked by all-encompassing low mood, thoughts of worthlessness, isolation, and loss of interest or pleasure in most or all activities. But this clinical description misses the deep, experiential horror of the condition; the suffocating sense of despair that can make life seem too arduous to bear.

Here's something else we can say confidently about depression: it is complex. The cause is often a mix of factors including genetic brain abnormalities, sunlight deprivation, poor nutrition, lack of exercise, and social issues including homelessness and poverty. Also, cause and effect can be hard to tease apart -- is social isolation a cause or an effect of depression?
