This is the perfect time to check out another fandom, it doesn't mean you have to follow it or give up any of your favorites. But by seeing what another fandom is all about, it will give you a chance to explore the rich variety that is out there.
A note of importance, you should not feel intimidated from joining a fandom. Anyone can be a fan of any show, book, movie, characters, etc. Unfortunately, there are some who don't feel very inclusive and go out of their way to ruin it for others. Fandom should be fun.
