Teen depression is often mistaken for the common mood swings of adolescence; however, depression is not just having "a bad day" or “being in a bad mood."
Depression is a prevalent condition in today's world. Some reports estimate 15-20% of the global population, or 1.1 billion people, have some form of mental illness (2016 population data). 2-6% of global population or 268 million people suffer from depression.
