The speaker's fear here is unusual. It isn't only losing the person they love, but losing the feeling of love itself. The first lines suggest the loss has already happened or is coming: "I had you" is in the past tense, so the person seems to be gone, and the speaker is left holding onto what remains.
What remains is memory, and the poem shows how fragile that can be. The speaker lists small, physical things: the sound of a laugh, a scent, a touch. These are the details that tend to fade first, and naming them feels like an attempt to keep them in place. The last line shifts slightly. The speaker fears forgetting not just the person but the fact that "I had such love," as if the experience itself might become unreal.
The mood is quiet, tender, and a little anxious. Short lines and plain words make it sound like a private confession, and the repetition of "afraid" keeps the worry close to the surface.
