"Passa de l'esperança al dolor i de la solitud al temor."
Traducción:Pasa de la esperanza al dolor y de la soledad al temor.
Well, it seems to me it means that (he or it) passes from hope to pain and from loneliness to fear.
It goes from hope to sorrow and from loneliness to fear
I concur that it is a bit puzzling. Anyway, this is a Spanish-based course and we should go back to it. Good luck!
