I'm not sure I agree that nothing helps... I'm a lot better than I was 2 1/2 years ago, as measured by ability to exercise and complete physical and mental tasks, reduced PEM, improved cognitive function/reduced brain fog, etc. I am not cured, and the treatment I've undergone has been significant and costly, but it has helped a great deal.
There's no magic bullet yet, and I doubt there ever will be. This disease is a complex, multiorgan system disease, where the immune, nervous, endocrine, cardiovascular systems, etc. are affected. It is triggered by a number of causes, creating a cascade of adverse events, which lead us to be stuck in this trap, and there is collateral damage along the way that must be cleaned up. No two of us are alike, so though we may be in the same state, we may have different things that need fixing along with breaking us out of the trap.
Things that have dramatically helped me, prescribed for many of the things on the lists above, are:
Methylating nutrients and glutathione
Valcyte
BCAAs and other amino acids
IVIG
Adrenal, thyroid, and sex hormones
NAD+
Phospholipids
HBOT
PolyMVA
