What about the supps I suggested to you? ALL your symptoms are to do with adrenal and thyroid weakness - low blood pressure, anxiety etc (due to mercury).
Dont forget to take extra sea/himalayan salt for your adrenals (it will raise your blood pressure).
Extra B5 will help adrenals too and at least 3000mg vitamin C a day.
Yes most people, including me have started on Andy's programme on our own, without a doc, but using Andy's book and the yahoo groups. I noticed you've been getting help there too, that's great, listen to what Linda says.
I know it's hard but you have to make a decision. You're not going to get better quick but you can alleviate some of your symptoms in the meantime.
Let us know how you get on, ok?
