I have recently been playing once more a piano piece that seems to epitomise despair (and also loneliness). Do not complain of overblown romanticism, this is bare bones music: Heller, Op.128 no.4, Einsame Blume. It is marked 'Sehr langsam' and begins with a bare melody, continually rising only to fall again; this is repeated with variation and is followed by rising phrases, each higher than the previous and each terminating in a dissonance. The music then drops to a repeat of the melody, now with minimal accompaniments after which the rising phrases re-occur, this time dropping from a high climactic note and a return is made almost reluctantly (despair indeed) to the opening bare melody leading to two bleak final chords.
