To foul up is human so there is not point in beating ourselves up over previous dietary choices. There is no question diet impacts on health. Sorting out which is the best option is more difficult.
I strongly suggest you take a look at the Greek Diet thread if you have not already done so. Some nutritionists have not yet grasped the Omega Three Six issue.

Omega 3 Fatty Acids in Clinical Nutrition - is an expensive book, [you could ask your library to get a copy] as written for doctors, is a bit technical but the bits you will certainly understand may convince you that Omega 3 and six fats are a serious health issue.
Nutrition and Physical Degeneration Weston A Price written in the 1930s is an excellent browsing book and truly though provoking.
