Have you heard of "Deliciously Ella?"
She is a food blogger who was diagnosed with an illness in 2011 and her symptoms sound just like yours. She healed herself strictly through diet. It might be worth to check out her story and see how much you two relate:

Go to her site, click on "about" and read under "my own health journey"
It could be very similar to your story.
Congratulations on taking things in your own hands, you sound like you are on the right path. Best of luck to you!
