What’s the correct term to describe this? [closed]
Disheartening
If something is disheartening, it makes you feel disappointed and less confident or less hopeful. -- Collins
Demoralizing
If something is demoralizing, it makes you lose so much confidence in what you are doing that you want to give up. -- Collins
