Hi @saddie and welcome to Mayo Clinic Connect. I can't imagine having brain fog and other symptoms for that long and not have a firm diagnosis. You will notice that I moved your post to the discussion you commented on earlier. The best way to connect with other members going through similar experiences is to post where they are.
I'd like to tag @growly, @tpatty5, @ldestella, @denisefinn and @jenlyn, all who have recently commented on their experience.

@saddie have you sought a second opinion or done any research on your symptoms that you could share?
