Sorry for you and your family Ken.
Two weeks ago a friend died in a car accident and almost two months ago my newphew died (5 months, heart failure). So if you want to talk about it, just PM me and IŽll give you a call.
Don't try to forget about him, try to think what a good time you had with him. Think that he'll always love you and remember you.
For me, it helps going for a walk along the beach on my own and cry a bit.
