I cannot imagine one of my kids dying. The pain, the loss, the anger, the realization that they are no longer here. I can imagine the grief and grieving though.
I have been exposed to death for many years and have had many extended family members die, along with clients. I am a social worker/case manager with seniors. As I have worked at the same organization for almost 18 years, I have had many clients die and clients that I have known for years.
Take a look at this article-it is a good resource/reference material.
