This is the first time you are rejected? If it's not, how do u
recover the last time?
If yes, mayb u can try the following:
1) Adjust your mindset. Tell yourself you deserve more and she
rejects u, its her loss.
2) Life isn't only love... Pick up some new interests like sports
etc.
3) Go party every night..
meet new ppl... maybe u'll find someone you might be
interested in.
4) Read a book...
5) Think of your future, your career, plan for it, work for it. It
might keep your mind from wandering to her again...
6) Go upgrade yourself with a coz. Diploma, degree, language,
computer, watever...
