Hi...not sure if you already found some help with your condition, but I know that high levels of arsenic and mercury generally indicate an issue with a genetic disorder of the MTHFR gene. I myself am heterozygous for MTHFR c677t and have been battling arsenic, mercury and aluminum toxicity. Please have your doctor run the blood work for this gene dysfunction. If your doctor has no clue about this condition, then find an integrative physician who is willing to work with you. You can also get a DNA kit from a company called 23andme for $99 and it gives you raw data on your genetic makeup, it will provide immensely valuable info on why you might be so ill and will start you on the path to healing. I know my journey to get well has been a truly difficult one...I am still learning every single day.
