There is no natural method for healing of Graves. A positive attitude and good spirit WILL help you tremendously, though. If you keep that up, healing can come faster

If you find healing through the process your going through (natural), then you may never have actually had Graves. It you have a true DX of Graves, then you have only a couple choices of care (which do not include what would be natural). You will not succeed with the natural approach with Graves. In fact you can put yourself in SERIOUS danger if you continue the path you have been on.
I know b/c I went through a stage with Graves where I truly was in denial about it. I, too, thought I could conquer it with the natural method. So, much that I had a SECOND thyroid storm b/c I REFUSED to take ADT's. I even went to a natural Doc...and he did blood tests that never related to Graves. Waste of money;( I thought that I could fix the issue with good food, lots of sleep, positive thoughts...I never really understood graves until I did tons and tons of research.
Really take the time to understand what your dealing with. For me, going through a thyroid storm was the most horrible time of my life. If you really have Graves, and you continue the natural method...you may end up with a thyroid storm. And I promise you that you will regret so much not taking the advice of a understanding Endo who will give you some options of care. Had I listened to my Endo the first time, I would NEVER have had a thyroid storm the second time. My lack of understanding put my life at risk. I had no clue the Graves was as serious as it is and that it needs immediate care.
I was told IMMEDIATELY by my Endo to have my thyroid ablated. That totally freaked me out....the only other option of choices for me was trying for a remission on ADT's. That was the most natural method for me at the time. I tried for 2 years and could not achieve remission. My goiter grew so large that it came out from my neck. I then choose RAI....and I'm on replacement now.
Looking back...I had very similar desires like you.
I continue a very healthy lifestyle: positive, eating good, exercise, etc. etc. I do take my replacement hormone every morning. I feel great and I'm so happy that I can now focus my energy on things I more interested in...lol
Be careful with the path your on....it could cause serious problems. Hope you find the care that you need.
