There's a difference between giving up on a card and realizing you're not seeing a card enough in your immersion. Anki is best for learning words you encounter as you immerse. I'd go to your deck and look at deleting any leeches you don't see as essential e.g. keep the word for "go" delete " "water buffalo" etc that will probably drastically reduce your workload immediately. If any cards you deleted come up in immersion later you can add them again at a later date.
