I finished my senior year early. but before, when I was in her class, I pushed her away, not intending for her to go away, and she abandoned me. Go figure.
It's been nearly three years since I last saw and talked to her.
She was literally my best friend for almost two years. We'd go out to eat. I went to her house. After she abandoned me it was the main reason for my depression. She's never checked on me. I've healed greatly but some days, like today, I miss her to the point I feel sick. Next year I hope to write to her and explain my BPD... I'd never heard of it when she was in my life. I didn't understand myself. She deserves an explanation for why I said and did the things I did. 
One time she called me a pain in the ass (while we were still friends.) She didn't say it just so she could be rude but she said something positive about me then, "...but you can be a pain in the ass." I shrugged it off while inside my heart broke. 
On days like this when I miss her terribly the fact that she said and thought that still crushes me. I still cry over it. And her. I used to think we never should have become friends. Well, yes, it was crossing the teacher/student line, but I’m so thankful we were.  I’m thankful she abandoned me. Hell, she told my mom she was doing it because she cares and that I’m better off when there’s distance between us. 
As much pain as I was in, it’s true. I’ve grown so much. I learned about myself. I recognize attachments now. 
But man I miss her so fucking much.
