Am I too old for this fandom?

I'm turning 29 this year and I get weird looks from people when I tell them my interests (FNaF of course being one of them) and it's really disheartening to hear so much. I love the lore and the gameplay of the games, read a few of the books, and I loved the movie. But everytime someone points out how old I am and calls me weird or more extreme things, it makes me wanna drop everything. I've been with this series since 2014 and I'd hate to leave it, but I'm just so torn.

Anyone else feel what I'm feeling?
