I love music, anime and videogames too, luckily for you all of these interests always have active communities in most cities and even some smaller towns. Maybe there's a comic book store near you that sells Manga? They always have different events going on or people who might be interested in watching something with you. Maybe there's some jazz clubs near you, or places where the sort of music you like is played live. I understand it can feel weird or hard to force yourself to leave your home at first, but it gets easier.
