Scarlett O'Hara for sure (that's where part of my username comes from!)

Her grit, determination and must I admit, selfishness, resonate fully with me. Also the extent of her selfishness ... the way she learns over the course of the novel how insanely unselfish others can be, and how much she is secretly ashamed of herself.

Lux Lisbon from The Virgin Suicides (Movie) - Other part of my username, lol

Her outer cheerful appearances hide a serious melancholic, destructive inner nature. She falls in deep love with a guy, is jilted, and resorts to sexual escapades to fill that empty hole. Like how I would get.
