Maussade – gloomy
With everything joyful, there is some sadness because it can and will all pass. Nothing gold can stay, etc. But with every sadness is also an undercurrent of joy, because sadness means that there was something to value and miss. Even if you don’t have it anymore, there is a happiness in knowing that it is at least imaginable. The worst is just feeling nothing - nothing matters, nothing is beautiful, nothing is worth it.
