The lyrics of Hey Monday's song Hangover describe the aftermath of a relationship that ended badly. The narrator compares the pain and confusion she feels to being in a car crash, and expresses disbelief that someone who seemed so good for her could hurt her so badly. She describes feeling physically and emotionally sick, unable to move on from the relationship and struggling to make sense of what went wrong. She feels like she is drowning, trying to keep her head above water while being pulled back towards her ex-partner. The chorus of the song expresses the idea that the narrator is suffering from a "hangover" caused by the relationship, likening it to the physical and emotional pain of a night of heavy drinking. She had hoped that the relationship would be something she could easily let go of, like a bad habit, but instead it has left her feeling broken and unable to move on. Overall, the song describes the pain and confusion that can come with the end of a relationship, and the difficulty of letting go of someone who has hurt us deeply.
