Read quickly, this single line is a statement about abuse, and it lands hard because it is so short. The speaker says someone "killed me with words," which suggests no physical violence at first, only cruelty spoken aloud. Then comes the second half: "turned my body against me." The harm doesn't stay outside. It moves inward, so that the speaker's own body seems to have become part of the attack.
The poem doesn't say exactly what that means, and that openness is part of its force. Judging by the wording, it could point to shame about the body, to illness or pain brought on by distress, or to the feeling of no longer being at home in oneself. The speaker sounds exhausted and hurt rather than loudly angry. There is no explanation, no plea, just a flat, final account of what happened.
The mood is stark and heavy. With so few words, every one of them carries weight, and the silence around the line feels like part of the injury.
