If you’re worried about leveling up, get some userscripts or use the new preview dashboard to see what you can’t fail (radicals or kanji) in in order to progress. Self-study quizzes or just primarily focusing on those items (You can also try ignoring vocab until you get the level’s kanji to Guru level) will let you get to leveling up much more quickly. By reducing vocab you can also manage your review stack much better, which will maybe lead to less stress.
In my opinion however, I find the vocab to be rather indispensable as in contextualizes the otherwise usually obscure kanji, especially once you reach higher levels. But I think in our case it wouldn’t hurt to just push through some levels to get your motivation up, then slow down again to catch up with the vocab.
Some suggested userscripts: Ultimate Timeline, Dashboard Progress Plus, Reorder Ultimate 2, and Self-Study Quiz.
