100% relatable.

Whenever I get hyperfixated on a new series, I always end up just consuming all the content I can of it. Oh, and the favorite character from that? Well, time to go scour the internet for extra fan content while I'm at it! And here's also 10 pieces of fan art done by me of them.
Then I'll sit and think of little silly scenarios with them while working on my math homework or something.
The only thing that sucks is when the fixation is towards your own OCs, because there is no new content unless you make it yourself. 😔 - Someone who has been hyperfixated on her own OCs for over a year now, with it just fluctuating between which OC in particular is the current fixation

It's normal, but definitely don't let it get to a point where it becomes an all-consuming obsession. If it's getting in the way of things like your relationships, chores, work/school, or self-care, you should probably dial it back a bit. And that can be a hard balance to maintain, but you just gotta remember that they're not real and things like self-care and work/school are more important than watching another 12 episodes of that anime or whatever it is.
