I am so glad you have asked this question. And so much more happier to hear that I am not the only one with the 'cold' feeling sometimes.
Long story short, my husband passed away September 25, 2004 (last year). He suffered from and battled for a year against leukemia. Bone marrow transplant, transfusions, chemo, radiation, the whole 9 yards, and STILL lost the battle. I was a complete mess, especially because of our 2 boys...Jacob 7 and Zachary 4.
As with many of you here, I have had other deaths in the family or friends that have passed away since, and I wonder what is wrong with ME when I can't shed a tear.
I think we all react in our own very unique ways to death. Death that is close to us, and death that is not close to us.
We are all different and we all handle things in different ways. let nobody tell you that you are cold or selfish. you are just being you and human!
