I agree with what @Jirachi has said 100%.
Level 8 is too early to reset unless you’ve been away for a large period of time, and the way SRS is designed is that if you get stuff wrong it’ll come up more often, so even if you feel like some words are “weaker” or less understood, they’ll just pop up more and eventually be in your long-term memory.
It’ll also give me a jumping off point to work on until I can afford my new subscription.
If you can’t afford a new subscription right now, I suggest using KameSame alongside WaniKani, even though you’re not subscribed right now, as far as I’m aware that just means you won’t get NEW lessons, but you should still be able to do reviews of lessons you’ve already done.
(Am I wrong? or is he unable to get reviews now, please someone confirm).
KameSame will help you cover all of your stuff from level 1-8 anyway and reinforce the learning.
Don’t give up, you’ve got this. The worst thing you could do right now is completely hit pause on learning Japanese*.
If I am wrong, and you cannot do reviews anymore because your sub has run out, I HIGHLY recommend downloading the “Anki” app, it’s free and you can input all of your Kanji / Vocab into it or find a WK deck.
If this is the case, please don’t leave WK, the forums are always here with open arms to answer any questions and help with your Japanese language progression.
Edit:
As a few individuals are trying to villainize me and accuse me of encouraging piracy I will clarify the meaning of “WK deck” here:
Summary
A WK deck is a Anki deck which follows WK structure (specifically the words / vocab) used at a specific level.
I have created this as an example:


(Imagine that, there are no mnemonics, crazy huh, not all decks contain mnemonics.)
The reason it’s called it a WK deck (which seems to confuse some people @gyroninja) is because it specifically follows the vocab / kanji that WK use for each level, the reason you would not call it a generic “Kanji” deck is for categorization, if you have multiple decks you don’t want to confuse them, and you want to make it clear to people who may want to use the deck of its contents.
TLDR: a WK deck follows the structure of WK’s leveling system, WK does not own the Kanji or Vocab used, so this is perfectly fine.
