Ok.. I understand. That could be the case too.
Your symptoms are the most common reported, so it's hard to say exactly what it could be.
What most people do to try to get to the root cause is cleanse. Colon, liver, kidneys etc. And supplement with the basics.. I just start with a simple centrum multi vitamin/mineral and then add in the Iodine recommended co factors & such.
Cleansing is something that almost has to be done routinely.... you don't realize how junked up the body gets until you've done a few and each time you wonder how is all this junk in me?!?
Do you have leukemia? I would imagine that would make you feel run down. What's the prognosis?
You should post on the Iodine VWT forum
