I agree with these previous posts: EVERYTHING is a learning experience. Pain MUST be experienced, it's good for your character. You learn about your behavior and what possible negative patterns you might want to avoid repeating in future human interactions (because it goes beyond romantic relationships). You also become strong on your own, if you allow yourself to heal and be happy without jumping into another relationship right away.
To get over my own breakup, I studied Buddhism and learned about the idea of non-attachment. A delicate balance of holding someone dear in your heart, while simultaneously severing attachment and just feeling peace and happiness, alone, and joy knowing that she is happy, in the world, with or without you. I also practiced Yoga twice a day, meditation, and pranayama (breathing techniques). This may seem unrealistic to you, but TRUST ME--you want to expedite your inner peace after a breakup? I highly recommend trying it. But I said it before and I'll say it again:
1. Work on your own happiness, alone and out of relationship
2. Elevate your skills in whatever arena you enjoy most
3. Focus on family and friendship relationship dynamics
4. Love yourself dearly, even if it takes you getting off your butt and doing charity work
5. Focus on fitness and body/mind/soul connection
6. Put loads of positivity and love into the universe
If it doesn't help quell the shitty feelings, it might produce GOOD FEELINGS in addition!
