The speaker begins with numbness, repeating "I feel nothing" three times, as if trying to convince themselves. Then the line shifts to "I feel pain," also said three times. The repetition makes both states feel heavy and stuck, like a thought that keeps circling and can't be shaken. There is almost no decoration here, just short, flat statements, which suits a person too worn down to say more.
The ending turns into a question: "Am I nothing / Or / am I just pain." That lone "Or" sits on its own line, like a pause where the speaker hesitates over two bleak choices. Neither offers comfort. Either they are empty, or they are made entirely of hurting. The word "just" suggests that pain feels like the only thing left of them. The mood is bare, tired, and quietly desperate, and the poem leaves the question unanswered, which makes it feel unresolved and raw.
