Sometimes just opening up and talking about whatever is bothering you to a friend, partner, colleague, or professional is enough to take the edge off. The simple act of putting your thoughts into words and bouncing them off another engaged individual can bring the issue into focus in a way that no amount of personal rumination can.
The death or personal tragedy of someone close to you, your own brush with mortality, debility, and illness, or relationship issues can all take on a new light with discussion.
Good to remember when things start to get dark.
