I've Lost my Son RUDRA

The heaviest weight for a man is- son's deadbody on father's neck. I have already picked the weight by myself. RUDRA... my beloved son, my angle boy has left me and my family on 06 September 2008. He was suffering with deadly Juvenile Myellomonocytic Leukemia which is basically known as BLOOD CANCER. I don't know how I can give myself a little satisfaction. I just prayed to almighty Allah to keep his soul in peace and let him enter the Jannatul Ferdous directly. I also want everybody to pray for him.
