Wide awake night after night, the woman in this short piece has a handy explanation: insomnia. The poem quietly shakes that excuse off. In the second stanza it points to the real cause, her "troubled heart," which won't let her rest. Sleeplessness is only the symptom. Something emotional sits underneath it.
The speaker seems to watch her from the outside, gently and without judgment, noticing what she won't admit to herself. The last stanza turns into a question: she wonders whether she will ever "find peace." That word reaches beyond sleep. It suggests she wants relief from whatever weighs on her, not just a full night's rest.
The mood is quiet, tired, and a little sad. The short lines and plain wording feel like thoughts drifting through a dark room, and the poem ends on uncertainty rather than comfort. We never learn what troubles her, which makes the feeling easy to recognize in ourselves.
