I'm not entirely sure which 'Kimmy Schmidt' you specifically refer to. There could be many people with this name. If you mean the character from 'Unbreakable Kimmy Schmidt', it's a fictional story about a woman who was rescued from a doomsday cult and tries to start a new life in New York City.
The 'Unbreakable Kimmy Schmidt' story is quite interesting. Kimmy was held underground by a cult leader for years. When she gets out, she has to face the modern world which is very different from what she knew in the cult. She is a very resilient character. She makes friends, tries to get an education, and has various comical and heartwarming adventures in the big city.
Well, if we're talking about Kimmy Schmidt from the show, her story is filled with themes of survival and self - discovery. After being freed from the cult, Kimmy is constantly learning about how the real world operates. She faces challenges like finding a job, dealing with relationships, and coming to terms with her past trauma. For example, she has a job at a Gyno - office where she has some really funny and awkward interactions. Her friendship with Titus is also a big part of her story, as they support each other through different situations in their new lives.
