Can you spare 5-10 minutes a day out of your wanikani time doing something else, like Lingodeer? That way you’ll see the kanji you’ve learned in a more cheerful less punishing and more contextual environment.
My first time with wanikani reaching your level was quite overwhelming, tons of data that sometimes felt like it was going nowhere except for crushing me under it.
I don’t know what is your end goal, but maybe choosing a short time goal that makes you happy will help you survive this phase. Wanikani is better as a supplementary app not the main or the only one, even though some people choose to use it this way, it comes with a cost.
I would really recommend starting with graded readers to bring your motivation up, and see that what you’re doing leads to something practical (hey look I can read Japanese!), for me that was a great motivation booster. I started with white rabbit (nothing like a depressing sad story for motivation boost?) I really enjoyed the you can read Japanese bundle.
Wanikani is a very punishing system and if you use it solely it will get to you unless you’re able not to take it so seriously. It’s hard, and it got to me the first time around.
Id on’t know if it helps, but I think it’s important to know the gamification can do that, and it’s not just you.
