Stop following any Harry Potter fanfiction websites or social media groups dedicated to it. Unsubscribe from newsletters or notifications related to it. If you have any fanfiction books or e - books, store them away out of sight. Instead, start exploring new genres like science fiction with works like 'Dune'. You can also try out new hobbies like painting or learning a musical instrument. This will fill your time with other creative and fulfilling activities and help you escape from Harry Potter fanfiction.
One way is to focus on other book series. For example, you could dive into 'The Lord of the Rings' which has its own rich and detailed fantasy world. Another option is to engage in non - fictional reading like biographies or historical accounts. This can shift your focus from the fictional world of Harry Potter fanfiction. Also, getting involved in outdoor activities such as hiking or cycling can take your mind off it. When you're out in nature, you're more likely to think about the beauty around you rather than fan - created stories of Harry Potter.
Limit your exposure to Harry Potter - related media in general. This includes not watching the movies or re - reading the original books for a while. Try to find a new TV show to binge - watch, like 'Stranger Things'. You could also participate in group activities such as a book club that focuses on different books. By surrounding yourself with different literary works and people interested in them, you'll be less likely to be drawn back into the world of Harry Potter fanfiction.
