有时，我们会告诉你“不，我没有抑郁症”，然后他们会微笑。可那是个伤感的微笑。

To the outside world, they give no hint of their problem -- often holding down a full-time job, running a family home and enjoying an active social life. But underneath they are suffering secret panic attacks, insomnia, crushing low self-esteem and even suicidal thoughts.

他们不会对周遭的世界显示出一点抑郁的症状——通常都有全职的工作、有家庭，社交生活也很活跃。但在私底下，他们饱受惊恐症和失眠的困扰，很自卑，甚至会想到自杀。

The ability to carry on with life despite everything is what distinguishes 'smiling' depression.
