<human>: Can you condense the text into a few key points?

We had been dating for just short of a year and everything had been going smoothly, we both go to the same university and definitely had a good thing going on. I had gotten sick of some things I saw as her having a bad and expecting attitude of me and decided that I wanted out. I also thought I really just needed some time to work on myself as I'd been going through a lot of stress, self worth issues and thought I needed to put my focus into school. I took a really lame way out and just kind of stopped talking to her for a while before we actually broke up which I think hurt her pretty badly.

 I know I did love her at one point and she was my best friend and I guess I just miss her. I've tried to apologize because what I did is tearing me up but when I see her in person I can't gather the courage to talk to her because I'm so ashamed. I don't know what to do about it because she probably hates me now, and even though I'm doing well in school it doesn't feel right, like nothing was worth it and I just pissed away the best relationship I've ever had. 

Is it worth it to try and reestablish a connection? I feel like I royally fucked up and don't deserve a second chance. anybody else been in a situation like this?
<bot>: I thought it would be a good idea if I broke up with my girlfriend to focus on school. Later regretting it thinking about what we had. Super lonely pretty sure she hates me no idea what to do.
