What's the best way to endure heartbreak?

Have a friend who is deeply wounded by a failed long term relationship. Such an awesome, accomplished, happy lady.. now more like a puddle with little to no appetite, boxes of Kleenex everywhere, and start trek reruns on the tv.

Of course, it just takes time for the heartbreak to subside or for the story to change.. but in the interim, what are some of the best way to spend heartbreak time?
