I know someone who was diagnosed with "laughing depression" or smiling depression.

Those who are most surprised to realize they're experiencing some form of depression are those suffering from “smiling depression.” Most people haven’t even heard of the term. The definition of smiling depression is: appearing happy to others, literally smiling, while internally suffering with depressive symptoms. Smiling depression often goes undetected. Those suffering from it often discount their own feelings and brush them aside. They might not even be aware of their depression or want to acknowledge their symptoms due to a fear of being considered “weak.” Suicide can be a particular threat for individuals suffering with smiling depression. Typically, people suffering with classic, severe depression might have suicidal thoughts, but not the energy to act on their feelings. However, those suffering from smiling depression have the energetic ability to plan and follow through. This is why smiling depression can be more dangerous than a classic form of severe depression.
