Dang...
Here I was thinking that I had a new beer drinking buddy in those northern towns - one never knows, does one?
To get where you want to go, the previous advice about getting in touch with one of the hospice societies is good advice. You have so much to overcome in terms of discussing the undiscussable - we all do. But here is where you get to be real brave - if overcoming fear is what you call brave. Stepping out of one's usual habits is not easy, but once you do you will find much freedom, those habits are really quite imprisoning and breaking them is such a joy. However, breaking the demons and fears inside requires quite a different kind of bravery, and one that is very rare.
There are stages that you will go through: shock, denial, rage, and hopefully acceptance. These stages are not necessarily sequential, although they tend to be. But some days you will experience all of them - other days just numbness.
There are books, one I remember is "Death and Dying", I forget the titles of the rest. They are all on the same shelf. In the same way that self-help groups are available to alcoholics or drug addicts, there are self-help groups for the terminally ill (and like any group there are those that will try to hog the limelight, but some of those quieter folks can be the salt of the earth). The hospice society can steer you in the right direction. There are also counselling services etc., again the hospice society.
This is very sad GF, to lose a friend before even getting to know him.
But then you know, it's rare, but sometimes those things just go away.
