How to explain depression 
Get diagnosed. 
If you feel that you may have depression, consult a medical professional first. Self-diagnosing a series illness like depression is not safe, since depression has serious side effects like angry outbursts, suicidal thoughts, and social isolation.
If you are under 18 or are a dependent, ask your parents or legal guardian for help finding a doctor. If you are over 18, your regular doctor will refer you to a mental health professional.
