What's wrong with my life now?

I broke up with my girlfriend of 3 years. Yeah doesn't sound like much but we've been together nearly 24/7. We shared so much memories and had so many things happen to us. It's not just coincidence. But then out of the blue she said "Hey, I don't think I can be with you forever." And you could guess the rest. I just don't know what to think. Imagine a girl you've loved for 3 years spent nearly everyday with and even lived together day in day out for a year to suddenly stop saying I love you to you. My soul is crushed. It hurts so bad. But she seems to be doing fine. How does she do it? Both of us were aiming for medicine in Sydney. And guess what? She managed to get in and I didn't. We studied the same way and all and yet my results were so so so so bad. I feel like vomiting and beating myself up because of this? Did she leave me because she can sense that I'll fail? I don't think so but ugh. The feeling. I feel so hopeless. So inadequate. In comparison the minimum requirements is a gpa of 9 out of 10 and a UMAT (Undergraduate Medical Admissions Test to study in Australia) score of 50. Ok. She got a gpa of 9.3 and umat of 56 and she got accepted. Me? gpa of 8.9 I did manage to get an interview though. And the worst part umat of 41. I didn't meet both requirements. FML so badly. I also can't believe I lost someone so smart and beautiful. She's just so beautiful and pure and smart it's so hard to find people like her. And she left me. Well she did it before my results came out so yeah maybe she sensed it deep inside. I still love her. SO MUCH. I can't stop thinking of her. H*ll I even look at her facebook everyday. But I was so insane with sadness a week after we broke up. She didn't talk to me. I had no one. Because we were in different countries. I just needed someone to talk to. Well I did send her a few long emails and asked where she was and if she could go online. She called me a "F*ck*ng STALKER". That killed me. I couldn't stop crying for days. So I just stopped going online. Then when I got my results I had the bravery to email her. We talked for a bit. And yeah she said sorry. I'm not sure what to do now. Well I haven't received an official reply from the university but chances are I can't get in. And I still love her so much and I want to be close to her in Sydney so I can be well friends at the very least. Problem is. Because of my result I can either go do another course in the same uni as her or do medicine in a uni in a different country. That does mean I have to be away from her for 2.5 years. I could opt to go back to sydney after that. So what should I do? I can't leave her either. I just feel so lost and confused now. Any advice would be great
