I was diagnosed with asperger's syndrome at age 13 (I'm 24 now). I never really bought into it, but at the same time I knew it signified something. Something was "off" about me compared to others. I went to a college that was very accepting of odd social behaviors so it was easy for me to buy into the idea that I was perfectly normal, and it was society that was "intolerant". But even there something was still a bit "off" and it became more and more obvious the closer I came to graduating. Once I did (barely) get my diploma I did some further investigation which led me to mercury poisoning. It took a bit of convincing, but after reading the literature (mostly Huggins and Cutler) and visiting sites like this, I could not be more certain.

I guess you could say my mercury poisoning manifested itself primarily in odd behavior (I'd drive my car in circles on the same road for hours, for example) and negative emotions as I've always been a very depressive personality. Physical symptoms have always been present, but only recently have they become bad.
It's kind of bizzare for me to accept the idea that all these negative thoughts and behaviors aren't me, but a toxic chemical inside my head. For so long I used to consider it just "my personality" even though deep down I knew something was very wrong.

What's my point? None really, just that you have to trust your own intuition about things. Each time I found a new list of symptoms for mercury poisoning I was shocked how well they described everything that plagues me from living the life I want to. Others would tell me I was fine, just a little "strange" but they liked that about me. If only they knew what it was like to BE me. The quackbusters can say what they want, they are no match for your own experience.
