I'm very sorry to hear about your difficult situation. You probably think your situation is strange but in the heavy metal (HM) chelation groups you'd fit right in. You really remind me of a young woman named KJ who is active in the Yahoo Frequent Dose Chelation group. She has gotten nice gains from detox. I'm sure she'd be happy to chat with you. If you are interested I could provide links to some of her posts in the group over the past couple of years.
I hope you are seriously considering adrenal issues. I think your doctor is right to consider a possible need for progesterone. You could get tested for its immediate precursor and the mother steriod adrenal hormone, pregnenolone. http://en.wikipedia.org/wiki/File:Steroidogenesis.svg
Progesterone is available as a creme.
Frequent urination is a symptom of HMs as well as adrenal problems--aldosterone. Do you crave salt or have CMP blood tests that report low sodium?
People who are sick with HMs, especially mercury (Hg) often have low levels of toxins in hair--they are retaining them, not moving them. However, their essential elements are often scattered in strange ways.
