deathfun: by the sounds of it, she may have some sort of feels toward you and is being aggressive because she is unsure of it or w/e that tsundere speal is. That, or she had some recent interaction with somebody else and is taking out some of that hurt on you.
At any rate, If she wants to talk to you, she'll talk on her own time. If she doesn't then she won't. Basically up to her at this point.
That's what I figured, and that's also what I respect
Although someone figured that she could also possible be bi-polar
EDIT: Entirely a non-issue, she apparently dropped me as a best friend a month ago and stopped trusting me. Fantastic
Lost another best friend attributed to me, but not entirely. I played my part in its downfall but I was working to fix my issues so that in the long run we'd be a better team. She chose to make up her mind about me and stopped having mutual trust, respect and communication
So my anxiety is gone, but I can't help but feel entirely ****. I don't know if I can trust myself to have close friends, or to love, or just any of that. I have few friends, and the number dwindles more than it rises
I'm glad that my friend still holds the keys to my firearms because right now I feel an emotional ****storm coming on
