Misery by The Beatles is a song about heartache and emotional pain following a breakup. The key themes involve feelings of abandonment, loneliness, and yearning for the former lover. The lyrics poignantly express the deep sense of sadness and despair the person feels, encapsulated in the chorus where the word 'misery' is repeatedly emphasized. One particularly poignant moment in the song is when the singer laments how they have lost all joy and only feel sorrow, highlighting the depth of their emotional turmoil.
