Jinx, alot of mercury toxic people have thyroid and adrenal issues,(me being one) and the tests that mainstream docs use is a blood test which isnt accurate and there are people walking around with thyroid/adrenal probs which are undiagneosed because of this.
Saliva tests are more accurate for this, so let them know, but i wouldnt be suprised if they refuse to do this. Last year i was at my doctors surgery with loads of symptoms and he sent me out to do a urine test and when i had gone he told my partner that i may have to be hospitalized if it carried on as i kept telling him that my depression wasnt really depression, like low serotonian, it was something else, i now know it was low T3 in my brain due to low thyroid. if i told my doc now that my depression has gone with taking T3 he would laugh because they just dont recognise this in mainstream medicine.
I still get the odd flicker of depression but thats the mercury in me, its more of an anxiety.
I really hope that clinic looks after you!
