What is life not worth living without?

I could not imagine what a parent has to go through to lose a child. One of my friends lost her baby to cot death and I watched her just fall apart.

I used to think that no one really knows until it happens to them, but after my daughter died I had many people come up to me and talk about their miscarriages and stillbirths. some had much more pain other just moved on. It affects everyone so differently its hard to really relate.
