I have just been thinking about this very experience/feeling. It's best to keep yourself busy, but the ultimately the feeling in never completely satisfied, you are merely distracting yourself. In finding productive things to do, and working on making yourself a better person, you feel very good about yourself, but I understand the feeling of passing time (waiting on the WAS).
It becomes easiest once you truly realize that you are the only one responsible for your happiness. This will be your turning point.
