Fallen angel's "Long Distance Relationship" is about missing someone so much that even waking up feels like work. The speaker says they've "just get used to it," but the details tell a different story: even blinking is hard when the other person isn't there.
To cope, the speaker pretends. Imagining the two of them together makes things easier, even though the poem pictures them divided by "deep seas" and eyes "blinded with dust." The speaker also insists this "isn't the end," holding on to some hope. Then the mood slips. The claim of getting over it gives way to a "slit" in the heart and a "pit" in the stomach, small words for a real ache.
The ending is the most vulnerable part. The speaker asks to be promised that they won't be left "dying / In the cold hard ground" while the other person only pretends. The mood is lonely and tender, with fragile hope and fear underneath.
