Sam M's "Words" is about the lingering damage of a relationship that ended badly. The speaker is still haunted by what an ex said, and the opening image of words that "pound in my head" makes it feel almost physical, like a headache that won't fade. The speaker also feels unfairly blamed: they "crumble" again and again while the other person never looks at their own part in it.
The turning point comes when a new person reminds the speaker of the ex. That memory leads to a painful conclusion, that they are "only good for two things," their body and homework. The bluntness of that list suggests how small the speaker has been made to feel, and the line "After that I'm worth nothing" is the lowest moment.
The ending is bitter and mixed. "Thank you for opening my eyes" sounds sarcastic, yet "screw you" and "breaking my heart" show real hurt underneath the anger. The mood is raw, resentful and unsteady, and the plain, short lines make it feel like an honest outburst rather than a polished speech.
