I Know Pain, Grief And Suffering

I'm kind of grieving. But I oddly don't feel anything. I know that's normal because people have different ways of grieving and dealing with death but it's weird when you actually experience it and feel nothing. I cared about that person and still do, and I miss them but I already feel fine. Again, I know this is normal but I can't help but feel guilty. It's almost as if I'm forgetting about them and that's not what I want.
