unhealthy orv fan that doesn't know what to do

ok so what I mean is that ever since I read omniscient reader's viewpoint i fell in love with it so much I bought the light novels right? So lately I've been so focused on this series that in class as soon as I've finished the task the teacher asked us to do I go and read orv or sometimes just start reading orv. This is affecting me deeply because i've been getting horrible grades not to mention i'm very bad at remembering useful things. Now normally I wouldn't mind and just move on but the problem is that if I continue to do this then i'll not get a job as a vet. Which means I can't help animals in the future. Also not to mention i also keep asking my friends what would they do if orv happened irl. But instead of answering they normally say "ASFDASFD you need to tell the difference between fiction and reality." I also keep wondering how I would survive if the apocalypse happens and stuff like that also whenever I bring up orv with my friends I act as if the characters are real for example "Oh guys do you think I can be a pro gamer instead of a vet?" "Pro gamer like that lol gamer you talk about faker?" "No pro gamer Yoo Joonghyuk?!" or "Man I wish I was as smart as sang-ah or I could be kim dokja's companion." Not to mention that I always say stuff like "The constellation ASFDASFD sponsors you 200 coins." “The constellation ASFDASFD is glaring at you.” I also have an obsession with kim dokja to the point where everything I write on has some sort of kdj on it like a kdj drawing or a saying from my king. This has gotten so bad at the point where on one of my english work it had us draw what fate and romance was so I drew kdj and yjh. And I also wrote an assignment about orv and twsa. I DON’T KNOW IF THIS IS A MINOR ISSUE THOUGH LOLOL ╥_╥
