Your story has touched me - and I dont know quite what I can say to help. But I would say it looks like your research is helping uncover a lot about what has happened with health issues with your family.
There are things you can do to help get rid of heavy metals from your body. a bit complex to go into in this note - perhaps a search of natural chelation methods may help you. Sometimes if a blood test doesnt confirm existance of heavy metals - hair tests can give some clues to what heavy metals are present in the cells of your body.
There are also doctors who undertake natural chelation methods and numerous naturopaths know methods as well. Its all a matter of what feels comfortable for individuals etc.
I live in Sydney Australia - but it appears heavy metals are causeing a toxic problem in our populations world wide - and particularly in vulnerable younger age groups.
