A melancholy nostalgia for something that perhaps hasn’t happened.
A pleasure suffered, an ailment enjoyed.
A strong longing for something that isn’t the present.
Learned a new word today from the movie: Nostalgia. I really like this one. In Brazil they actually have a day to celebrate this.
In Brazil, the day of Saudade is officially celebrated on 30 January. –wiki
Also from same wiki page:
Saudade is a word in Portuguese and Galician that claims no direct translation in English. However, a close translation in English would be “desiderium”. Desiderium is defined as an ardent desire or longing, especially a feeling of loss or grief for something lost. It also has a meaning of having feelings for something that we no longer have and wish very much we did. Desiderium comes from the word desiderare, meaning to long for. Connections between desiderium and nostalgia have also been drawn; the former can be seen as expressing the latter for things that can’t be experienced any more, or things that someone may have never experienced themselves.
I like the Plutchik emotion wheel shown in the right sidebar also. Nice handy reference if you’re a writer.
