Who said anything about me letting go of the world - for you to take over? :naughty:

Been There, done that. I broke off a friend (not gf), went into depression. I needed to hear from him, "he is over me". the moment I heared that, its not that bad. V.strange - i tell you. How this works. Just miss sometime the "friendship" I had.

Anyway, you do get over it. That is the right advise though:
Change ur life. your friends/habits/anything to everything you can. Keep yourself busy with something that you like and is positive. Reward at the end of something is the biggest incentive to keep doing it.
