The speaker is angry at a comforting lie. Someone keeps promising to always be there, to "water" the speaker during hard times, but the speaker no longer believes it. The word "despise" is blunt and leaves no room for softness. It's not the absence that hurts most, but the false reassurance that came before it.
The image of drought and crops carries the poem. The speaker imagines the hard days arriving just as the other person is busy tending their own life, their own "crops." The poem ends on a dash, mid-thought, with "to notice-", so the sentence never finishes. That cut-off feels like the speaker trailing away, or like the very neglect being described: the person doesn't even notice.
The mood is bitter and quietly sad. The short lines and lowercase style make it feel like a private, tired confession rather than a loud accusation. The title, "eimaan," seems to hint at faith or trust, which fits a poem about broken promises.
