One idea could be that Fem Harry Potter runs away because she feels suffocated by the expectations placed on her at Hogwarts. She might head to the Forbidden Forest where she discovers a hidden magical community that has been living in seclusion. This new community could teach her different forms of magic that she was never exposed to at school.
After running away, she could start a new life as an anonymous witch. She could use her skills to help Muggles in secret. She might use magic to heal the sick or prevent disasters in the Muggle world. This new life could give her a sense of purpose and also make her a more well - rounded witch as she learns about the Muggle way of life and how to integrate magic into it in a more discreet way.
