How do i deal with heart break?

This will be long but PLEASE BARE WITH ME! Ok so first off im 16 years old. I had been waiting for the right girl to come along for a while. So back in october of '09, i met this girl who (at that time i didnt know), would mean the absolute world to me, again she was my first girlfriend. So we have been together ever since, (about a year and a half). The first year of us being together was great but she moved about 30 minutes away from me, so it turned long distance. we loved each other very much, but things were getting just a little stressful because (long story), i couldnt drive to see her whenever i wanted to and her dad didnt want her spending the night anymore, even though she had done that plenty of times before she moved away. So i kept trying to tell her that we DONT HAVE TO BE A STATISTIC OF A FAILED LONG DISTANCE RELATIONSHIP. But it was hard to have her believe that. Then last night (May 3rd) she ended it :(((. We had the absolute best times together, everytime i hear a song (basically no matter which one) i think of her. We were on the phone and i just started balling my eyes out because AS SHE WAS BREAKING IT UP, Its like our while relationship flashed right before my eyes, from the very first few weeks of me knowing her to that moment last night. Im so heartbroken right now! I remember the very first time she hugged me and i still get erflies even to this day! I remember our first kiss too, it was the best feeling of my life! In 09 i had a crush on this other girl but she led me on to something that wasnt real, so i felt that my girlfriend had saved me basically when we met. We had so many good memories together. And alot of my friends are moving far away, and her breaking up with me is starting to make me feel even more lonely, im homeschooled btw. I dont know what to do! Every little thing reminds me of her! I tried to do everything in my power to make her as happy as she could, but now i feel like failure. Please someone help! Idk what to do !
