Feelings of hopelessness, pessimism
When you are in a depression, you may not be able to see your way out. It may feel as if there is no light at the end of the tunnel. You may begin to lose all hope for things improving, for life getting any better.
“When you’re in the middle of it, you don’t know when it’s going to end. You can’t even see the light at the end of the tunnel; it’s just not there. You know, you look through the tunnel and all you see is darkness.”
—Jimmy Brown, Firefighter
