A recent TED Talk, by Kevin Breel, a young man who suffers from depression and has become a mental health activist by sharing his message, defined this insidious disease better than I’ve ever seen or heard.

“Depression does not mean you are sad when everything is going wrong in your life. Real depression means you are sad when everything is going right in your life”.

We all think we know people who are may be suffering from depression. Using this definition as a measure it may be a way to suggest they seek the professional help they need.
