First off let me just say how sorry I am for your loss

There is no greater pain then loseing someone you love...
There is no <i>normal</i> way to feel after an event such as that, but some people have tried to put it into stages so it can be understood greater.
There is a thing called the 5 stages of grief, and while it is by no means a reliable guide to "how" grief works, it can shead some light on some things.
The 5 stages are:
- Denial
- Anger
- Bargaining
- Depression
- Acceptance
what you are going through and the feelings you are having seem like you are going through the Depression stage of your grief.
Sometimes it takes a while for the full force of what is happening around us to break through into us. It can take days, weeks, even in some cases years, to fully come to blows and terms with the way things have changed.
A newer concept of grief is that of TEAR
T = To accept the reality of the loss
E = Experience the pain of the loss
A = Adjust to the new environment without the lost object
R = Reinvest in the new reality
As you can see there is no right of wrong or wrong way of feeling in a time like this, but I hope that this infomation takes a bit of the weight of your shoulders.
