I was widowed back in '02. If there is anything you want to talk about; please feel free to PM me.
Do know that grief is a very individual thing. It may have stages, but we all go through them in our time and own ways.
The numbness is a mercy of sorts: it allows to you get through day to day without collapsing.
If anyone offers help; take them up on it. Remember to eat as regularly and healthily as you can. Drink water and/or decaf liquids during the day, and hardest of all when it feels like you've been punched in the gut...BREATHE.
"One day at a time" doesn't necessary cut it with this. It may take one hour at a time. I can remember getting through some days a breath at a time.
