Mary62708's "Regardless" is about missing someone who is gone, and trying to carry on anyway. The speaker says the sun will keep rising and setting even when "you aren't here." That sounds like acceptance, but it also sounds like a hurt person reminding themselves that life doesn't pause for grief.
The most honest moment comes when the speaker admits their mouth says "completely different things" from their heart. They seem to be hiding what they feel, perhaps pretending to be fine. The moon image softens this. The other person was the speaker's moon, a light in the dark, while the speaker "played the darkness." The poem suggests the speaker may have been the difficult one, or at least the one who was lost.
The repeated lines make the poem feel circular, like a thought the speaker can't stop going over. The mood is quiet, regretful, and tender, with a little stubborn resignation at the end.
