The anatomy of grief

Once again I am face to face with grief. The sort that wrenches everything apart. The sort that shreds the fabric of normality.
When the dust settles and the pieces fall back into place, they are never quite ‘in place’. It is a different reality. One that requires another getting used to.
Grief changes people. I know that for a fact. But does it change our intrinsic nature, or merely our world view? Is it possible to go back to a time of innocence, before the fact? I look into my children’s eyes and think not. Even innocence is altered forever.
