You my carbohydrate laden friend have answered your own question.
This is what I went through twice with my ex, but actually only felt like you are feeling once.
The second time it all happened I had it figured out.
Lets take a quick look.
how the hell do you get over someone you love who doesnt love you back.
Well, THERES your problem. Why waste a SECOND loving someone that doesn't love you back? Love isn't love unless its mutual. If she isn't going to give you the consideration do not give it to her. Try as hard as you can to realize that the relationship is over, but your life definitely isn't. When I was in your shoes both 2 years ago and 5 years ago, at first I though it was the end of the world because she WAS my world. Then I realized that I WASN'T her world. Not even close.
Now, an abused dog will keep coming back for more, and how often does the abuser say "Oh, how sweet! I kick him and he still loves me!" Never. That person does not care if you love them. Don't be that dog. Don't hang on just because its all you know right now. There is a lot more out there.
After my split with my ex I was sad at first, then I realized that I was no free to truly find out what I wanted, and to find what I wanted. Its out there. You have to be willing to find it because it will not just come to you.
Take the opportunity NOW to be in charge of your life, and to improve yourself. It will hurt for a while, but don't let it consume you any longer than it has to. Pain like that is a mental cancer, and once it gets so big, it can be impossible to stop. Don't martyr yourself, don't sacrifice yourself, just heal, grow stronger mentally, emotionally, spiritually, and move forward. Its hard to move forward when you're looking backward.
A wise man once said, "You know I'm bad! I'm bad! You know it! You know it! You know! You know! You know! Shamon! And the whole world has to answer right now, so I'll tell you once again who's bad!"
Good luck
