" Dr. Webb says that losing a sibling is oftentimes much harder for a person than losing any other member of the family. "A sibling represents a person's past, present, and future," he says. "Spouses have each other, and even when one eventually dies, they have memories of a time when they existed before that other person and can more readily imagine a life without them. Likewise, parents may have other children to be concerned with--a future to protect for them. To lose a sibling is to lose the one person with whom one shares a lifelong bond that is meant to continue on into the future. "
