One of my characters is a 12 year old girl. Her single mother is an emotionally abusive alcoholic. She used to be a happy drunk, but her younger daughter died in infancy (haven't decided how, but it had to do with the mom's alcoholism) and it pretty much tore them apart. Now the girl tries to avoid her mother as much as possible, such as by coming home late. The plot is kicked off when she finds a badly wounded, brain-injured vampire and decides to take him home and take care of him. She's a very unique personality. Here are some of the strange things about her: * she is unusually open-minded about the supernatural, so when she finds a vampire she basically thinks 'I always said it was possible for vampires to exist' * she doesn't hesitate much before deciding to feed the neighbor's yappy dog to the vampire * she lies a lot, volunteering lies when not saying anything would be more effective * she identifies the vampire with her dead baby sister, and gets emotionally invested in the idea of taking care of him, to the point where she finds it upsetting when he starts to recover * even though she's only 12, she steals her mother's alcohol on occasion and gets drunk So, what kind of psychiatric disorder might this kid have?
