In most parts I think about death that it is only natural. Now this sounds little harsh, but I think that best thing you can do with dying is simply let go. Usually we are more attached to our own feelings than person him- or herself so letting go should be a mental process.

When loved one dies the best way is to continue ones life with the best he or she can, suffer as feeling is very powerful emotion but to let it rule is not very productive.

I have buried few friends and a parent during my life, and my way to handle the situation is to understand how it is the most natural thing and I as well will die some day. When I remember it, I remember also to respect that I am still here living and enjoy my life until it ends as well!
