To tell your story.
You have to get it out. You have to share it. There are feelings you have that must be expressed. There are details that must be heard. In the beginning you are forced to do this as family, friends and others find out about your child. Then hopefully you have a few trusted people in your life that will allow you to tell your story, usually over and over. Even if you meet someone in the grocery store and you feel inclined to tell them what happened, do it!
Think of it this way - as much as you need to tell your story, the world needs to hear the lessons you’ve learned from loss.
