Karen Bassey's short poem describes anger that has already done its damage. The speaker says the rage burned "deep" inside, and the word "tormenting" suggests it was not a quick flash of temper but a long, painful suffering. By the end, nothing is left of the speaker except ashes.
The image that stays with you is the second one. Ashes keep their shape for a while, looking whole, but they are empty and fragile. The speaker says they remain "in one piece" in just this way: still holding together on the surface, yet one breath away from disappearing. The final line, "Until blown to nothing," leaves that threat hanging, with no sign of rescue or recovery.
The mood is bleak, exhausted and quietly fearful. There is no shouting here. The calm, flat tone after the burning makes the feeling heavier, as if the speaker is describing the aftermath of an emotional collapse and waiting to see whether anything will survive.
