Throughout the song, the repetitive chorus emphasizes the sense of being forgotten: "I'm forgotten/I'm irrelevant/I'm insignificant." The individual feels overshadowed by others and lost in the crowd, questioning their own existence and wondering if anyone truly notices or cares about them.
The song also touches upon the contrast between external appearances and internal struggles. The protagonist may present a façade of strength and confidence, but deep down, they're battling with their insecurities and the fear of being forgotten. The line "No one can hear me, and I can't breathe/I'm invisible, they can't see me" highlights this disparity between the outward appearance and the inner turmoil.
The song also explores the idea of seeking solace in music and finding an outlet for emotions. The protagonist finds solace in the creative process, using it as a way to express their feelings and connect with others who might understand their pain.
Ultimately, "Forgotten" conveys the raw emotions of someone grappling with feelings of isolation and insignificance, longing for recognition and connection in a world that seems to have overlooked them.
