Death of a Son or Daughter is the worst of the worst that can happen to you
You immediately enter in a state of Grief, Bereavement, Loss, Loneliness, Desperation, Anger,S hock, which I classify as Symtoms of Reaction to Trauma and they will effect you in many ways,but unfortunately the reality is you just have to go along with them as best as possible-its a natural prossess with no time span.
Stay in Touch with this website and you will not be alone.
Your may be able to obtain books giving advise on on The loss of a Child, death of a son,daughter, grief bereavement,advice,depression,councelling,trauma,shock,mourning,find how to cope with desperation,hurting,and all that comes with it, but I feel through only experience or talking to parents further along the path that some kind of comfort may be found in realising you are not alone.
Other Bereaved Parents and Groups dealing with Bereavement are probably more apt. and the rest of the time you really have to fight it yourself-sometimes not even family can help.
