Belgarath, my thoughts are with you at this extremely difficult time..
I had to go through the pain 6 months ago when my dad suddenly passed away, and I was unable to grieve initially as I had the funeral to organize.
I felt numb and I had to remain strong for others, I cannot imagine how you feel losing your beloved wife.
In time things will become easier, and you will be able to get yourself back on track, even though things will never be the same again!
Take your time and make sure you find some time for yourself and your family. Come back when you are ready. We will be here when you feel ready to return, and if you ever need a chat I'm a PM away.
Take care buddy
