I hope you don't find this harsh as it's not ment to be.  God isn't to busy to answer, he just doesn't exist.  Don't diminish someone's life with the focus in the wrong area.  Death happens, it sucks, but don't focus on the pain or the lack of attention from a higher power.  Be hurt because a loved one is gone but remember that there can be no peaks without vallys, you can have no high points in your life if you have no low points to compair them too.  Even the bible makes this point, Adam and Eve could not have known what they lost in the garden of eden until they were banned from it.

Find strength in yourself, friends and loved ones, the question why won't get any easier but it's better then waiting for an answer that will never come.

I'm sorry for your loss.  Take care.
