there was a girl I was friends with in high school who was not only a pathological liar, but a probably mentally ill. She would cut herself (but had no scars) and talk about how her estranged father was abusive. She claimed to be a 4000 year old succubus ("that's why boys are always so attracted to me!" she was attractive, but was also a slut). We put up with most of her bullshit until our senior year when she went around saying she was pregnant, then miscarried. Then, after her boyfriend (who she was beyond obsessed with) broke up with her, she went to a party and had drunken sex with a 17 year old boy (witnesses who accidentally walked in said she was on top) then claimed he raped her so her ex would come back to her out of sympathy. She ended up earning the nickname "Susan, the Whore Queen of Narnia" (from some podcast my friends saw, I don't know which one it was). She got so scorned at our school, she transferred from the best school in the area to a school that called themselves "the drug academy."

so yeah, we don't really talk to her anymore. Luckily, as far as I know, the boy she accused of rape never got officially charged.
