The speaker admits to something honest and a little unsettling: they can't always tell what they're thinking. Instead of being stopped by that confusion, they promise to try again, and even allow for a small, hopeful "maybe... I'll even laugh." The ellipsis feels like a pause to catch breath, as if laughter is possible but not guaranteed.
The second half turns toward light. The speaker will "shine a light, glowing like silver," reaching only "to the limits of my hands." That limit matters. The glow isn't grand or all-powerful, just as far as the speaker can reach. The comparison to the Aitken basin, a vast crater region on the Moon, suggests something dark and hollow that still holds a quiet, pale shine. Judging by the title, the poem is set in November, which adds a cool, subdued feel.
The mood is gentle, tentative, and quietly determined. It's less about feeling better than about choosing to keep going.
