Quite honestly, the best advice I can give you is: Get over it. Looks like she didn't even really like you anyways.
Judging by the pics, you aren't that old. (16?)
Your best bet is to just stay available, you'll find somebody.
Edit: How to get over it
1 ) Stay away from any memorable places.
2 ) Block your thoughts if you start thinking about the relationship, if you are lying down..quickly stand up.
3 ) Start looking again, a good way to get over it is to find another girl. Plain and simple.
4 ) Find something to do, go play with your friends. Baseball, basketball, video game sessions, anything. Have fun.
5 ) ...I...you could...always...go gay.
