In fact, many people who experience a low mood and a loss of pleasure in activities manage to hide their condition in this way. And these people might be particularly easy to suicide. While smiling depression is not a technical term that psychologists use，it is certain to be depressed and manage to successfully mask the symptoms. The closest technical term for this condition is atypical depression: It can be very hard to spot people suffering depression because they may seem like they don39。t have a reason to be sad — they have a job, an apartment and maybe even children or a partner. They smile when you greet them and can carry pleasant conversations. In short, they often put on a mask to the outside world while leading seemingly normal and active lives. Inside, however, they often feel hopeless and down, sometimes even having thoughts about ending it all. People with smiling depression put on a happy face to the outside world, but they can experience a lift in their mood as a result of positive occurrences in their lives. Other symptoms of this condition include overeating, feeling a sense of heaviness in the arms and legs and being easily hurt by criticism or rejection. They are also more likely to feel depressed in the evening and feel the need to sleep longer than usual. With other forms of depression, however, your mood might be worse in the morning and you might feel the need for less sleep than you are normally used to. So how can they break this circle? A starting point needs to be known that this condition actually exists and that it39。s serious. Only when we stop ignoring our problems because we think they39。re not serious enough can we start making an actual difference. Then we can find purpose by taking the attention away from ourselves and placing it onto something else. Feeling that our lives matter is finally what gives us purpose and meaning — and this can make a significant difference for our mental health and wellbeing.（1）What do we know about people suffering smiling depression?
