She's acting like this all of a sudden for no reason?

I've been friends with this girl for about 7 months, we met due to an eating disorder, we're both in recovery and go to the same school.. When we first met, she was encouraging me to recover. I took her for granted and didn't recover, and she kicked me out of her life and bashed on me for two months before apologizing and we became really close, and I started recovering. When school started, she became distant, like she's doing now. I don't know what it was, and finally things got so tense between us that we started saying things indirectly to each other, finally she messaged me this really long message apologizing, acting like she didn't do anything, but apologized and we got close again. That lasted for about two months.. Now she's acting weird again. It happened after I told her that I started working out to tone up after the weight gain.. I'm not sure if that had anything to do with it. She's competitive and an exercise addict.. But she would act just fine when I would talk to her. She started acting like I don't exist again, and she started sub-tweeting me on Twitter again. I said on Twitter 'I did it before, and I'll do it again' and she favorited that tweet.. And I found out that she was stalking my Tumblr page, probably looking to see if I said anything.

When we get close, she still doesn't treat me completely like a friend. We never hang out, she barely talks to me in school.. And I don't even have her number, we talk over direct messages on Twitter.

What do I do? My feelings are really hurt..

It might be something to do with her being competitive. I suggest you sit down with her, have a chat and just ask her whatever it is that is making her act this way.
