Life isn't as disheartening as it would be if it lasted longer.
Doing things that were of no value to any one was so disheartening.
The day was worse than its predecessor, inexpressibly gloomy and disheartening.
This was disheartening, but at least it taught me to begin at the furthest point in future.
But nevertheless it was a hard blow--a disheartening blow--to all of them.
