Four short stanzas follow the same pattern, and each one treats a human experience as something with a beginning and an end. The speaker lists love, crying, anger, and finally death, and says the same thing about each: I will feel this until I stop, and then I won't. The structure is almost like a rule or a formula, repeated so steadily that the feelings start to seem interchangeable.
What the speaker feels is hard to pin down, and that's part of the effect. The tone is flat and matter-of-fact, as if they're accepting that nothing lasts. Love and anger are huge emotions, yet they get the same plain treatment as death. That can read as calm acceptance, or as numbness, or even a quiet weariness.
The word "Finally" closing every stanza adds a sense of release, but also of repeated endings. By the last stanza, death sits in the list like one more passing state. The mood is stark, quiet, and a little eerie.
