 or some signs someone is hiding their depression. Number one, they're pessimistic about the future. When you ask secretly depressed people about their plans, they would either act dismissive, curt, or avoidant. Number two, they have a hard time concentrating. Do you often lose their attention when you speak with them? Are they losing their train of thought during conversations way too often? Number three, their body undergoes big changes. Do they complain about pains and aches around their body? Gaining or losing weight are some signs of depression, as well as back aches, digestive problems, headaches, and chronic conditions. Number four, they get unusually quiet. Does it feel like their energy has been sapped for seemingly no reason? Number five, they keep conversations surface level. Does it sometimes feel like they have a brick wall put up? And number six, they smile to hide their pain. What makes depression so sinister is the ease with which one can hide it all behind a smile. Have you seen any signs of hidden depression that your friend may be facing?
