Everyone relates and deals with death different, there is nothing wrong with how you cope and deal with it.

I myself have dealt with sudden deaths in the last 2 years....it took me 6 months to cry over one and the other I still havent cried or anything over...I find I tell myself alot they are just on vacation and not coming home.

If it doesnt bother you and you knwo your coping with it in your own way. I wouldnt worry
