Reminds me of Paul's Case by Willa Cather, about a young man who ends up jumping from a bridge in front of a train.
When the right moment came, he jumped. As he fell, the folly of his haste occurred to him with merciless clearness, the vastness of what he had left undone.
The suicide, as she is falling
Illuminated by the moon
Regrets her act, and finds appalling
The fact she will be dead so soon.
