Mistaken Belief #5: If you're not sad, you're not depressed

The Truth—Sadness (clinically known as depressed mood or irritability) is just one of nine criteria for major depressive disorder outlined in the Diagnostic and Statistical Manual of Mental Disorders 5, the go-to reference book on psychiatric illness. The other eight: loss of interest in activities you previously enjoyed, significant changes in weight or appetite, changes in sleep, fatigue or low energy, change in activity levels, feelings of guilt or worthlessness, trouble concentrating and thoughts of suicide. An official diagnosis of depression requires five of the nine persisting for at least two weeks, but depressed mood doesn't have to be among the five.
