It certainly does, I just tried putting my own emotions to the back of my mind when my son died, to be there for my Missus. But the fact was/is that I was just a 17 year old kid without a clue on how to deal with it, and still to this day at the age of 33 I still haven't dealt with it.
It is a very different kind of grief to losing anybody else... I cant control the grief i feel from losing my son... I barely knew him yet im inconsolable over losing him. Ive lost a brother, nephew and grandparents and friends yet it is nothing like how i feel over losing eden.
