Thanks everyone! I kind of felt like I was maybe being overly sensitive about this person. Forgive is a lot easier than forget, and trust is even harder. So far she hasn't shown me that she deserves my trust.

As suggested, I've been sticking to the light topics with her and being incredibly vague about any chance of getting together. Honestly though, if she's just a shallow, fair weather friend then I don't think confronting her about the past will accomplish anything. I'm not going to get any satisfaction out of it if it only confuses her.

At this point I think I'm going to just be open about all my issues as they come up; depression, GAD, OCD, psychosis, everything, and just she how she reacts. If she freaks out and runs then it's a problem solved. If she shows any kind of willingness to try to understand or at least accept me, then maybe we can be more than superficial 'friends'. I'm betting that she throws bible verse memes at me and runs though.
