The song "Black Hole" by Ella Henderson revolves around the idea of heartbreak and the lingering feelings that remain after a relationship has ended. The lyrics describe how the person she used to be in a relationship with often comes up in conversations with her friends and how it affects her emotionally. She expresses her frustration and sadness, as she wishes that she could also say that things are going well for her. The chorus emphasizes the deep emptiness and void that the breakup has left in her heart. She confesses that she has tried various methods to cope with the pain, such as praying and seeking inner peace, but nothing seems to work. She realizes that she cannot fill the gap left by her former partner with material possessions or distractions that she doesn't truly need. The song highlights the difficulty of moving on and how the absence of her ex-lover has created a significant void within her. The lyrics also reflect on the memories and happiness that her former partner took away when they abruptly disappeared from her life. The laughter and joy that used to fill her are now gone. She bares her vulnerability, explaining that she has made countless efforts to bring her former lover back to her, but to no avail. The song's title, "Black Hole," metaphorically represents the empty space and emptiness she feels inside. She longs for her former partner to realize that she is the person they need, but understands that filling the void is not an easy task. The song's lyrics emphasize the lingering impact of heartbreak and the struggles of trying to move on without closure or resolution.
