2 pieces of advice I have for you. #1, game chicks. It serves more than one purpose. First, sucess brings back your swagger, and second, it forces you to get involved in little mini relationships upon which your attention can be focused. And if you're focusing on some new challenge, you're not focusing on the heartbreak.
The bonus occurs if you actually game a chick who has potential to replace the one you're hurting from.
It also helps me not to ignore what I'm feeling. Knowing why you feel a certain way gives you the power to change how you feel. I used to feel like my feelings were out of my own control, you just feel them until something changes how you feel. But you have control of yourself, and you feel what you focus on. If you focus on how bad it hurts that you lost someone, you'll make zero progress. But you have the control to focus on something else, you just need the will to do it, and the know how to assess your feelings, acknowledge them, and move beyond them. It takes work, but I can tell you from recent events, it's well worth the effort you invest in it.
Good luck.
