It’s probably just going to take time! But also, if you add some fish into your diet, you could keep having omega 6 fats and the ratio would be fine. The omega 3’s in nuts arent converted very well, whereas the omega 3’s in fish are way more bioavailable.
Pro tip if you dont like the taste of fish: shred 2 thawed frozen salmon filets, then add 1 to 2 tablespoons of minced ginger (or more. You literally cant have too much 😂) and a generous amount of garlic. Form into a several patties and fry. Eat with chili oil and avacado. It cuts the fishy taste beautifully, and it’s wildly healthy.
