I understand what you are saying, I think. I think it is different for each separate person and it is for me anyways, if I had any kind of loving relationship with the person.
When my mom was killed in the plane crash, I was still living at home and it was very, very hard. With my dad who I had disconnected so many, many years ago there was nothing to grieve really. I felt weird about his death, but also relief that he could not ever hurt anyone ever again.
I think it gets really complicated at times with each unique death.
I know our society is not big on grieving for too long a period for most people.
I am sorry that I do not have anything more than this to try to answer your questions. You will understand how to grieve when you lose someone you really love I think. You will just be grieving I think. Maybe someone will come along that has better answers for you.:hug:
