Omega 3,6 and 9 in Flax oil?

Just getting swamped with the posts on the "fatty liver" previously, so much info to digest.
I feel I may be in the same catagoy, maybe. But, I do eat low fat and always have, which I know is not good ...especially the good fats.
The past year I could not tolerate Omegs 3 fish oil most of the time, would get more anxiety. . . so unusual and opposite of what it should have done. Don't know if it was the sourse "fish" but, wonder about Flax oil?

But, too, does not most all nuts and seeds contain high amounts of copper? Wonder than it thre is a high concentration of copper in Flax oii?

So, it is my understanding ( please let me know, as I really don't know) that if one's bile-gallbladder, liver is not functions well, it will not digest and utilize fats intake well?
I would like to be able to take some form of Omega 3,6 & 9, as it is so beneficial for the brain too.
Thanks all,
Paulette
