Stress is the reason that tipped me into RA, I know it. Even though technically, I have removed most (say 80%) of the stress in my life, my immune system cannot go back to its original balance and I'm still working on this by getting myself treated for all emotionally aspects and stress in life.
I remember reading on Dr Mercola's article that mentions that all RA that he encountered has an emotional stigma and you can only recover well if you can free yourself/treat yourself of this emotional trauma. He suggest Emotional Freedom Technique (EFT). You can learn free at http://www.thetappingsolution.com/
Hope this can be useful for you.
