a little bit crazy

it's about a teenager with mental health issues. She is very smart, but she doesn't exactly talk to people very often, accept people who she has to talk to like her parents and her teachers. people think she's a little bit crazy, and that is absolutely fine with her. She likes having her schedule, it keeps her calm. but when someone interrupts her perfect routine while showing interests in the things she finds interest in, she has no idea what to do because even a perfect routine and complex mathematical equations can't prepare someone for the complexities of romance, or the dangers of an apocalypse.
