Losing a child is the grief people are most afraid of, and they are right to be. It runs in the wrong direction. A parent is not supposed to outlive their child, so there is no script for it, no expected order it fits into, and no point where it is finished.
If this happened to you, nothing on this page will fix it, and it would be an insult to pretend otherwise. What this page can do is tell you the plain truth about what you are in, name some of the specific things that make it harder, and correct a few myths that get repeated at grieving parents. If you want the general shape of how grief moves, we cover it in grief is not linear. This page is about the particular weight of a child.
