While society has increasingly recognized depression as a mental health disorder, many people still confuse sadness with depression, or vice versa. Depression is not sadness or self pity, nor is it something one can simply "shake off". It is a mental health disorder that has a network of causal factors, including biological, psychological, and sociological components. Depression can be debilitating and it may impact all aspects of one's life. It can erode a person's sense of what is meaningful and valuable, and turn a world of vibrant possibility into a world of monochromatic, lifeless, routine. Misconceptions about what depression is can unintentionally create barriers to treatment.
