The speaker feels trapped in darkness and unseen, and the poem keeps circling back to why. At first it seems that nobody reaches out, but the speaker realizes that no one can see them in the dark. Then comes a harder admission: the face they show the world is a mask, so people can't see the real person even if they look. The speaker longs for a "valiant Knight" who will remove the mask, rescue them, and bring warmth.
Each hopeful wish is answered by the same refrain, "then I realized," and a doubt follows. How can he save me from the bottom of a deep hole? What if he never comes? The mood is lonely and heavy, but not defeated. The repeated "Despite all of those" shows the speaker refusing to give up, and the last lines settle on a quiet, secret hope that light will come.
