<human>: Can you give me the gist of the text in a nutshell?

I don't get it. I don't get why I am still in love with her. It's been 7 months and I still can't stop thinking about her. She broke up with me because she thought she wasn't good enough. This honestly hurt me extremely because I've tried everything to be happy and we never argued in this relationship until she said that and I wanted her back. 

  Also, struggling with depression at the time and almost it leaving since I had her, after she left I've been stuck in a huge depression episode that just subsided around December 2015, for about 5 months, but I am still considered depressed and I take medicine daily. 

  I've only seen her twice, both at some AnimeCon with her performing there or me seeing here there. The most recently one was about 6 days ago, she performed for some k pop dance contest and I promised myself that once I see her perform and she finishes, I'd be over her. But, that wasn't the case, tears rolling down my eyes and myself bawling with 7 of my friends watching the show and not noticing. 

  I noticed every little detail in that dance. Her adorableness, how into dancing she is and basically all the small things. I feel in love with her again after I said I want this to be a good bye. I didn't approach her because I knew it wasn't the right time.

 I don't understand, I don't fucking understand why I still like her, why I feel so guilty, why I cry over her everyday, why I can't keep myself sane with out thinking about her. Sorry guys.
<bot>: I can't get over my first relationship because I feel guilty for not being there for her and her thinking that she's not good enough. I wish I had another chance.
