Clinical depression, also known as major depressive disorder (MDD), manifests itself differently in everyone. Some of us are genetically prone to experiencing the disorder during our lifetime. Others experience clinical depression as a result of traumatic events or stressful school, work, or personal environments. Changes in brain chemistry and hormones can also cause the onset of clinical depression episodes.
Symptoms of clinical depression vary greatly in the population that this mental illness affects, which is about 6.7% of the US adult population (or 16.1 million Americans over the age of 18 each year) according to The Anxiety and Depression Association of America (AADA). Symptoms >may include feelings of emptiness, fatigue, irritation, agitation, anxiety, and failure to enjoy activities which you once considered ‘fun’. Those who are clinically depressed may experience any combination of these symptoms due to a clinically depressed mental state.
