Like everyone has said, I think one of the most important things is to take it day-by-day. i like the wound healing analogy myself. the fact that you're acknowledging your feelings is good - I think it's good to say to yourself "I know it feels like I can't go on without her, but that's not true". In a little while, or a long while, depending on you, you WILL look back and say "remember how upset I used to be?" It will feel like a whole different era of your life. But you'll make it worse if you cling to that period - if you feel like you've done all you could do, it's time to try as hard as you can to let go.
