Would it help to identify the actual qualities in her that you are drawn to and realize that with certainty there are other women who possess the same qualities that are alone and would respond to you?
The human mind is not that comforted with probabilities...this is why gambling is such an addiction, the risk (and payoff), entrenched within uncertainty, is the appeal.
* with certainty, there may be others just like her, with doubt, there may not be likelihood that he shall have another like her.

I know ya'll got the skills. This is why during a prior meet-up I felt the need to give jenocyde props and remark that her entrepeneurial spirit in all things meant that she was an "opportunity actualizer." --Course, as the ENTJ present pointed out, this could justify bank robbery.

Accept it. Let yourself mourn for a fixed amount of time that you feel is appropriate (typically a month for heartbreak), and then move on. And by move on, I mean that even though your heart is sore, you don't wallow in it. You acknowledge it, let yourself feel it (ie. accept it), and just do your best to ignore it.
During the mourning period, I suggest cathartic music. Listen to people singing about what you're going through, or things that are way way waaaayyyy worse (for example, Gorecki's 3rd Symphony movt. 2, where a teen in a gastapo prison sings to her mother who she'll never see again, telling her not to cry... Jesus, imagine being that mother and never knowing what happened to your kid, only knowing that she's somewhere suffering... ouch). This helps you keep things in perspective, so you remember that your life isn't over, and you're not alone in your sufferings, etc.
