Never should you have to bury your son ...or your daughter. As a parent we would give our lives for our children and do everything to protect them and not being able to protect from this horrible tragedy gives a feeling of helplessness. But you know what might give you a little comfort and  I dont' know if you believe in God but I do and he teaches that death is an enemey and he will brought to nothing. And jesus also promises that those in the memorial tomb will hear his voice and come out. The bible promise to eliminate death and everlasting life. Faith is frail, but doesn't kill easily. Having that hope and faith in God and do his will, he'll give us the desires of our heart. Hope the days to come are easier as it goes on.
