I would get very very drunk so I will be so damn hangover that I would forget the pain in my heart, just focus on my physical recovery. Then I would listen all musics that can make me cry, shout, lay down on the floor, and why not, dance. I would put passion in my pain as I did in my love, but give me a deadline. Suffering is good, for a day or two. Suffering too long is not good. I would definitively take holidays if I can and go away for a week or a month. I found physical distance very useful to take distance with any painful situation.
