The common news that trigger individual empathy all over the world obliviously - suicide.
From my own experience and perspective, most of the famous news that caused such issue, sometimes we are disillusioned by the word "success", it's like whenever we reach there, and found out, that wasn't really the case. Most of the people when they are able to reach that spot, found themselves to be alone, and no one to share real emotions and bonding, especially happiness, sadness, issues, etc due their believes which can be egos, self-pity, guilt, loneliness, no longer fill purposeful, feeling not good enough and so on.
It can be also the peer pressure of the society on how we labelled people as "failure". Exploring both the "success" and "failure", people tend to forgo about "being content" and "joy" and "happiness". Today's world is mostly judge about fulfilling material desire which toxic if not being checked. There are also the thoughts on how one individual self-labelling to their past.
Both of these extremes will cause depression and ended up in suicidal state.
It can't be identified through the face of a human being, but through the windows of their eyes. Humans are not made to be alone, we are design to be keep in touch and connection vertically and horizontally. Of course, it depends on a person principle each individual's hold. Either being religious, , being rich, being poor, anybody a person can still be in depression mode.
The most important part, make sure you have someone to share your happiness, sadness, etc together with, and discarding your ego. It comes a long way to heal for those who being through depression, so don't give up.
May you find your purpose in life, and fight for it.
