But the truth is there are levels to this. I grieved when I lost pets. The pain I felt was very real and deep, but it didn't really compare to the pain I felt when I lost my grandparents. I was very close to them, and I was devastated when they died. That pain, however, was not even close to the level of pain I felt when I lost my daughter. That is life-changing pain that one never recovers from.
So I like the idea of shattered glass because it allows for acknowledgement that all grief shatters us. Some grief, like perhaps a pet loss, might just break us into a few big glass pieces, relatively easy to glue back together. Other loss, like that of my daughter, shatters you into a million glass pieces. No amount of time or effort will put you back together. But you can take the pieces and shape something from them. That something can still be beautiful and have a good life, but it will never be the same thing as it was before.
