I'm not trying to be sarcastic when I say this...

but what makes this so hard is that mercury can cause symptoms of isolation and hopelessness regardless of the situation you are in. If its bad you can feel isolated and hopeless even if you are with the person you love the most, and they understand what you are going through.

I think why some people don't get sick is both genetic, and due to the nature of the fillings themselves. Huggins mentioned the concept of oral galvanism, which is a electrical current that runs through the teeth (and releases mercury if you have fillings) and I think some people have stronger currents causing much more mercury to be released.

For me, my family has very strong physical genetics and they are very resistant to physical diseases, but they are very suseptible to anxiety and other mental disorders which mercury definitely triggers.
