Distract yourself with other things. Maybe focus more on sports or schoolwork. You could always find someone new but you want to be sure that you are ready for a new relationship and are going into it for the right reasons.
You can get over a break up fast by cutting all communication and avoiding your ex at all cost. You should also try pre occupying yourself with other stuff in order for you to stay distracted from the break up.
Have something to do every day. When i got over my break up, my friends took me out to ball games, to a pottery studio, to bowling, shopping, all sorts of crap to keep me entertained and forget about him.
