Our culture tells us that we should fight hard against age, illness and death: "Do not go gentle into that good night," Dylan Thomas wrote. And holding on to life, to our loved ones, is indeed a basic human instinct. However, as an illness advances, "raging against the dying of the light" often begins to cause undue suffering, and "letting go" may instead feel like the next stage.
One of the hardest things about life is recognizing its various parts. I mean, we never really notice pregnant women until our wife becomes one, or the plight of the handicapped until we break an ankle or leg, and crutches help us see more clearly.
