A buddy of mine did the exact same thing, swore he'd watch two episodes a night and then binged the whole East Blue saga over a long weekend. He said the moment that got him was when he realized he was thinking about the crew during work the next day. That's how you know it's got you, when it follows you out of the couch. @harris.vera is right that fighting it does nothing, so maybe just set a timer or something if you have stuff to do. 14 is nothing yet, you're still in the part where it's fun instead of a full time thing.

Wrote my first letter after my wife died and my supervisor said it sounded too polished. Like I was writing for the file instead of for her. That hit hard. Started just writing what I actually wanted to say, messy parts and all, and the families noticed the change right away. One mom told me it was the first letter that felt like a real person wrote it.
