Underneath a cheerful surface, the speaker describes someone in deep pain. On the outside, people see a smile and a carefree attitude. Below that, the poem moves down through layers: first remorse, a hate for life, and a wish to escape, then a "broken soul" who simply waits for the suffering to stop. The title, "Ghost," fits this idea of a person who is present but not really seen.
The feeling is exhausted and hopeless. Words like "darkness," "fear," "misery" and "despair" pile up, and the image of a sea suggests she is being swallowed by them. The mask is the key image. It hides her real feelings, but holding it up is a struggle, and the short, broken lines make the effort feel fragile. The ending is quietly alarming: when she finally breaks, the pain "becomes known." The mood is heavy and sad, with a sense that hiding pain can only last so long. As the subtitle warns, it deals with painful themes and may be upsetting for some readers.
