I'll add my two cents even though I don't use EFT anymore as I feel no need to anymore.
I started seeing a spiritual healer at the begin of june and I can I totally rely on the energy unbalance cause of CFS.
Perhaps you wouldn't believe it, but my healer is seeing the exact same energy problem between AIDS patients and me (I'm the first with CFS he ever treated I think, though he saw a lot of fibromyalgia, all of which were cured)
The link between CFS and AIDS is the heart chakra, it regulates the thymus gland, the heart of our immune system. I had a massive hole in this chakra, that was my main problem. My aura was like 1/32 inch tick and it should be at least 1 inch and a half inn healthy individuals. He said I was about to die in a couple years at this rate (of cancer most likely). I felt I was already dying back then so no big surprise.
Most acquired diseases during life like are energy problems, this is not something specific to CFS. CFS is just as legitimate as a disease than MS. I believe that a retrovirus cause the symptoms and that it's the first things the immune system has to fix to heal of CFS. But first the immune system have to be stronger otherwise it will never have the strenght necessary to fight this fight and here comes energy healing.
The only thing I did over the past 3 months is to have 5 sessions with him and drink about a liter of dynamized water with a special programmation to increase its energy. Nothing expensive here, at all.
I started have pimple all over after 2 sessions, my mood came to normal a couple weeks into treatments. I finally wanted to socialize again, though I was still to weak to get out. I communicate with a lot of people from my past and it was a great expensive to WANT to be in contact with the outside world again and feel pure love for life. Amazing experience!
I started fighting opportunistic infections after a month and a half I'd say, I had flu for the first in years 4 weeks ago and a kidney infection with a cold only 2 weeks after that, how strange! After that came a massive herx where I was bedridden with massive pain in all my muscle and lots of twitching, pain never was a major problem for me over the course of the illness.
I was able to walk longer and longer (well until the viruses came along of course) and now I seem to be over this intense healing period. True healing hurts!!
It's too soon to say I'm cured but a miracle is happening, I'm not the same I was 3 months ago, at all

I encourage everybody to find the best way possible to boost their vital energy, it does a lot to give a kick start to your overwhelmed immune system.
