Syazwan_29's poem is a single, breathless sentence about missing someone. The speaker says that the pain of not having this person makes him cry and blow his nose, and the plain, physical detail of the nose-blowing makes the sadness feel real rather than dressed up. Nothing is described beautifully here; it is simply messy, the way crying actually is.
There is also a tug-of-war inside him. He wants to "be a man and just laugh," which suggests he feels he should brush the hurt off and stay strong. But he can't. What he can't fix is the habit of going "blank" every moment, a kind of numb emptiness where thoughts and feelings seem to switch off. The poem doesn't say who the "you" is or what happened, so we're left with the feeling alone.
The mood is raw, quiet and a little helpless. The lack of polish and the run-on line make it sound like someone confessing in a low voice, without trying to hide anything.
