When will the pain ease

Hi,im new to this group and wanted to share my feelings with you.I
lost my wife to melanoma in june 2006 age 35.I have two children
(boys) 9 years and 4 years old.Even though it`s been 2 years it seems
like yesterday our boys and i had my darling Katherine swiftly takin
from us.I miss her so much and there`s not to many days where i don`t
have a cry and wish she was here to give her a big hug.It was just so
cruel to see her go from the bubbly woman that loved life to someone
so sick.She was my best friend and we did everything
together,fi****ng,camping walking on the beach and the list go`s on.I
just feel so empty without her by my side and am really struggling
looking after the kids on my own.I`ll be pretty good for a week or 2
but then it only takes something to remind me of her or one of the
boys say something about mummy and then my hole world seems to fall
apart once again.My family and friends have been very helpfull but
last week i lost my temper with my dad.He wanted me to go out to a
friends house with him and i didn`t want to because it was one of my
bad days.Then i got the "you have got to try to move on" talk.I guess
what im trying to say is should i be trying harder to move on or maybe
get some professional help?.Im begining to wonder how long will this
hurt be so strong.I think what makes it harder for me is trying to do
so much for the kids where Katherine did all that before and now i
have to do it all.Thankyou for listening,Paul
