Nikky's "My Fault" is a short, raw poem about heartbreak and the guilt that comes with it. The speaker begins with a thought about love: the pain doesn't depend on how long a relationship lasted, but on how deeply someone loved. It sounds like a lesson learned the hard way, as if the speaker is trying to make sense of why this hurts so much.
Then the poem turns inward. The speaker admits they knew they "shouldn't have fallen" for this person and did it anyway. That admission leads to the final lines, where heartbreak and pain are both labeled "my fault." The repetition feels blunt and a little defeated, like someone saying it over and over until it sinks in, or trying to take control of a hurt they couldn't prevent.
The mood is sad, regretful, and quietly self-punishing. There's no anger at the other person here. The speaker turns all the weight back onto themselves, which makes the poem feel honest and vulnerable.
