The look of glassy dilated pupils

I have to share this since I knew exactly what was being described. From:

She said she felt unstable and every once in a while I'd look at her and her eyes just weren't her. I started to cry and then she asked if I was ok and showed remorse and changed like a switch. She raised her voice a lot and seemed very stressed because I mentioned earlier she had been seemingly more distant lately. When I was hanging out with her before her mood improved I had such bad heart palpitations it hurt really bad. I wish I didn't meet her I don't know if this is what she has though

Read through the comments. All too familiar.

Wow.  The comments were actually helpful for me.  This summer I really wondered if my uBPDw had a dissociative disorder as I felt like I was talking to such different people.  But they weren't separate personalities with different names, etc. 

"With the borderline, their core self retreats and an over exaggerated aspect of themselves is presented to you instead"

No idea if this is technically correct but rings so true to my experience - at least lately.
