What to do now after break up?

Little background: my girlfriend broke up with me about 3-4 weeks ago, 2 weeks ago we talked and gave each other space to see if maybe she'd decide to try again with our relationship. I already knew I wanted to give it another shot so it was up to her. Yesterday we talked and she didn't want to try so here I am now. I deleted her phone number from my phone (even though I've already memorized it) and deleted her from my facebook and myspace so I don't have to see whatever she's doing. Someday maybe we'll rekindle a flame or whatever but for now I really don't want to see or hear of her at all. What should be my next steps? I'm a college student so winter session and spring session will be keeping me kinda busy. This is really hard after a 1 year, 2 month relationship that was going really well. She just broke up with me without warning so it hit me really hard and now I'm really missing her even now. Any help would be greatly appreciated.
