U sounds very similar to me. I have tried everything and I'm still suffering. I am trying a new clinic that is world-known for biofilm erradication and chelation. They have a long wait-list, but if they accept my case (they screen before they accept a new patient), then I'll let u know what they do and how it helps, for it may help u too.
I hope things turn around. I'm in your same boat and it's frustrating that we can fly to the moon and do all these other amazing things, yet we can't seem the figure out the human body.
