I think the body would go into shock for awhile, but no one should be able to tell you how to feel, the body will take in account how to deal with this, and you will deal with it, in your own special way, people deal with things in a whole range of different ways, It's just some are better than others, and unfortunately some people choose difficult ways for themselves to deal with it.
But whatever does happen, never think you're not feeling anything, because you will, even though it may be nothing.
I'm very sorry for your loss.
