The speaker begins in a state of exhaustion. Sleeping little, they break, and the poem insists this is ordinary: "as anybody would." That phrase lowers the drama. Falling apart is presented as a human response, not a personal failure. Yet the breaking is also strange, because the speaker splits into pieces that are "infinitely other," as if the self scatters into countless versions that no longer feel like one person.
The sea image takes over in the last two lines. Being "infinitely at sea" suggests being lost, adrift, without fixed ground, but it also echoes the idea of sounding the depths, where sailors measure how deep the water is. Instead of panicking while others probe how deep the trouble goes, the speaker sings. The mood is fragile but oddly defiant: tired and unmoored, yet finding a kind of freedom, even beauty, in coming undone. The poem seems to suggest that breaking can still make music.
