Maria's poem is a single, unbroken sentence, and that suits what it describes: a feeling that keeps running on without finding a place to rest. The speaker is longing for one person's touch, which was powerful enough to make their heart "come to a stop." That phrase can mean overwhelming love, or it can mean something closer to shock, and the poem leaves both possibilities open.
Since that touch is gone, the speaker tries to fill the gap with other people. The word "fulfill" suggests an emptiness that needs filling, almost like a hunger. But the attempt fails, and the poem ends plainly: "it does not feel the same." There is no anger or dramatic outburst here, just quiet disappointment. The mood is wistful and a little lonely, with a sense of being stuck. The speaker knows the search isn't working, yet keeps going anyway, which makes the feeling seem all the more honest and human.
