Vegim's poem captures a moment of anxiety as it happens. The speaker is alone, typing, and so overwhelmed that they want to smash the keyboard on the floor. Soon the anger gives way to something more physical: tears, a racing heart, uneven breathing. The speaker needs someone, and the line "You said you'd be free" suggests that person promised to be available but has fallen asleep. That leaves the speaker to cope alone, which seems to make everything worse.
The mood is raw and urgent. Short lines, stuttering sounds like "tha-thump," and the repeated "Stop. Stop. STOP." mimic a pounding pulse and a mind that can't slow down. The wish for the heart to stop is not necessarily literal; it reads more like a desperate need to escape the feeling. The last two lines turn toward hope, as the speaker admits they need to start healing, which ends the poem on a small but real step forward.
