You seem to be in the beginning of your japanese journey, right? Your brain doesn’t have a concept of how japanese words and sentences are build yet, so naturally it’s still very hard! It will get easier once your brain has settled in and became used to japanese. But that takes a while. So don’t be discouraged just yet.
So what can you do until then?
I’m also on team read, reveal and grade. Seeing words in context and additional repeating other words and grammar points in the same sentence will help your brain getting used to japanese faster.
Take it slow. I don’t know how many vocab and grammar points a day you’re going for, but maybe scale it a bit down. Review the vocab for the day or week a few times a day with for example with the cram function or your own notes and sentences you’ve written.Just five minutes here or there, whenever you have a natural pause or a bit extra time on your hands.
Don’t feel ashamed to make the most ridiculous mnemonics you can think of. Spending this time will help you making those first words stick better.
While immersion like reading a manga or watching anime with japanese subtitles is probably still a long time for you, think about light immersion, just to help your brain out a bit.
Duolingo is actually great for that! You get a few sentences with high repetition of words and grammar and they always read the sentences aloud for you, so your brain gets reading, listening and meaning in one go. While you can’t expect to become fluent in japanese using only duo, it’s a nice addition especially for light immersion in the beginning. If you haven’t deactivated romaji yet, you really should, so you get used faster to hiragana and katakana. The free version is more than enough for that.
If you enjoy watching anime and you haven’t done so yet, I would suggest switching to japanese audio with subtitles in your preferred language. Not only is the voice acting best, but you can get a happiness rush everytime you recognize a word or even a whole sentence! Sometimes you even start to recognize words you haven’t learned yet. Sometimes you get a vague sense of a word or grammar point, but it only clicks if you get it here in the reviews. All those are positive learning experiences, guiding your brain slowly to get used to japanese.
If you are more the grinder type of person or want to see faster results, I suggest trying your hands on a textbook like genki. Older version of genki are oftentimes found in (online) libraries, so access is easy and free, and bunpro also has a path for genki and other textbooks.
With learning japanese, there are basically just to big hurdles to overcome: first the beginning until you have basics down and second to keep going even if your motivation wanes.
Good luck, you can do it!
