I started Wanikani (and studying Japanese) in December, and had a solid two month streak of doing something daily. However, a couple weeks ago I got ill and had no energy, and thus didn’t study for a little bit. “I’ll just rest for a few days” I thought. However, those few days quickly turned into a couple weeks, and now I’m having a hard time finding motivation and getting back into the routine of doing reviews (which I now have 500+ of…), lessons and overall studying. I even got myself the first みんなの日本語 book, but haven’t even been able to start the first chapter yet. I still want to continue learning Japanese and my plans of eventually traveling there and learning the language enough to have conversations hasn’t gone anywhere, but right now I’m just having a really hard time getting back on the grind. Any tips or words of advice from people who’ve had a period like this and how should I try to resuscitate my routine and motivation of learning? Thanks in advance!
Don’t do any new lessons until your review count is firmly tackled.
I recommend to hack away at the reviews, a little every day - try to do a week or so without excessive amounts, to get back into it.
If you plan to start みんなの日本語, don’t think: Chapter, think half a page and just do that as your goal and then pat yourself on the back.
A little every day if you can and: every day is more important than the amount.
You made it to Level 7 already - that’s an achievement in itself!
Think you pretty much just have to jump right back into it
I second this!
Also, if worst comes to worst and you would find yourself completely unable to get the motivation, remember that reset is actually an option.
Level 7 is a great achievement, but if you reset to level 1 and start doing reviews immediately, you’d be able to get back pretty quickly.
It’s always better to start moving right away – even at the cost of having to go back than to keep sitting still and trying to muster the courage.
Now, I’m not saying you have to do reset – I would be very glad if you manage to get through this without having to do it, I’m just saying that it is also an option, and a better one than doing nothing.
Anyway, whichever you choose, best of luck with your studies! 
I agree with @DaraM18 - NO NEW LESSONS!
But here’s the thing, new reviews will keep piling up as time goes by while you try to reduce your review count! If you don’t do enough reviews, your review count could actually go up instead of down.
To avoid that, enter Vacation Mode to stop your review clock, i.e., no new reviews will accumulate while in Vacation Mode. Whenever you’re ready, exit VM, do your reviews, and enter VM again. Keep doing this until your review count is down to what you can manage (zero would be ideal) and then stay off VM and restart lessons. Good luck 
You’re definitely not alone in feeling this way sometimes. I too have experienced periods of time where my motivation to keep studying or working on my japanese has gone down, and I’m sure many have felt this way too. I think it’s a normal feeling to have so don’t feel bad about it or too down because of it.
My suggestion for trying to get out of this slump is to think of something “fun” to do or something different that you might find exciting and engaging. If your mind is stuck on doing hundreds of reviews or piles of flashcards, or reading chapters of potentially dry textbooks (みんなの日本語 is completely in japanese I think, so it seems like a mountain to climb for a beginner), then it might be difficult to convince yourself to grind it out or power through it all.
As for what you might find fun/exciting or engaging, well that depends on you ofcourse. I can only really speak for myself and for me it’s using an AI like ChatGPT as somewhat of a personal tutor to help me translate and breakdown everything I come across in my favorite jrpgs and manga. I use the text scanner/recognition feature on my phone’s camera to copy paste the Japanese in subtitles or speech bubbles and feed it into ChatGPT. I then get explanations about what the kanji/vocab means and what kind of verb conjugation and grammar was used. I can then be inquisitive and ask many questions like “why was this form used?”, “why not this instead?”, “could this have worked too?”, etc. and this helps me feel much more engaged than reading theory in a book or powering through flashcards. Ofcourse this has its limits and you need to be careful about the information you are reading, but honestly this has been really helpful for me and even teachers in classes make mistakes and aren’t perfect either.
Once you feel engaged and excited to be learning again, then jumping into textbooks and SRS feels much easier because your willingness to see and do and learn more skyrocket.
So maybe try a few new things and see if that spark gets reignited. I wish you all the best!
I think part of the resuscitation is to reconnect with your goal. So say your goal is to be able to have conversations when you travel to Japan in 20XX. Spend a little time working back from then to see what you might need to know six months or a year prior, and so on back until you get closer to now, and then work forward to figure out you can get to that first step.
And then realize that the learning plan will probably change. You may not pick the right resources for you. The only things you can control are your effort, and the biggest factor in that is your desire. Really internalize your goal and if it’s important enough, remind yourself that it’s okay to do less study once in a while (or take a day or two off when life demands), but that you want to go and speak Japanese in Japan and doing that means you have to work at it.
The tl;dr : know your goal, and try to make small steps when you can’t make bigger ones. You can only fail when you quit, otherwise it’s just a minor delay.
Buy a three month at a glance calendar and hang it someplace where you can’t help but glance at it daily. Also buy a big, fat, red marker.
Every day you study AT ALL (do NOT be hard on yourself) mark off that day with a big red X.
Now play “don’t break the streak”.
Sounds stupid, but it works. You’ll be amazed how much it bugs you to break the streak once you’ve got 2-3 weeks in the bag.
Thank you everyone for your advice! I’ve given it some thought and I think resetting might be the right choice for me. It’ll give me some time to build up the habit and momentum again without too much stress, and doing the lower levels again wouldn’t do any harm anyways. Honestly, it does feel a bit frustrating. Not sure why but resetting feels like “admitting defeat” in a sense. Even though I understand that it’s a dumb mindset, I still can’t help but feel like that. I’ll give it a little more thought, but if I don’t come up with another plan I’ll reset. Going around in circles on what to do would just delay getting new progress even more, so I guess I just gotta commit sooner than later.
If it helps, remember defeat is basically the end. If you made the decision to walk away, that would be defeat. Resetting is an admission that for whatever reason, you need to step back and come at it again from a different angle or different frame of mind or whatever else, but coming back means you’re not defeated - the most you could say is it was a mistake and you’re going to learn from it.
