My stories are not nearly as dramatic, but that's probably a good thing.
I had a "friend" who was going through recruitment (we hold it in January) and all during fall semester, she talked about how much she LOVED Kappa and knew all these sisters and couldn't wait to be one of us. I had just initiated the year before, so I was pretty excited about Kappa too, and didn't think it was that wierd. Well, January comes and I am really pulling for this girl, and two sisters announce they were her (neutral) orientation leaders and she was a BEYOTCH to them. It turns out she was incredibly manipulative and totally fooled those of us who were her "friends". She was obviously cut and never even made eye contact with me again!
A girl from my high school was showing some signs of wierdness/instability at the end of senior year. She assumed everything her sister had done would be handed to her on a platter. (not an easy act to follow - captain of the cheerleading squad, homecoming court, now a successful lawyer). Her sister had been in one of the best sororities at UGA and she thought she was "guaranteed" a bid. She went to each of the houses and said things like "So I hear you're the bitchy sorority?"
She ended up dropping out of school altogether and living at home again. Last I heard she was taking pre-recs for law school at a local college.
