so that's why i'm crazy then.

I am sorry to say, but it is actually a serious issue unfortunately

Alfred Stock, a noted chemist, reported becoming very ill, and eventually tracing his illness to his amalgam fillings and the resulting mercury intoxication. He described his recovery after the fillings were removed and believed that amalgam fillings would come to be seen as a "sin against humanity."
Hal Huggins, a Colorado dentist(previous to having his license revoked), is a notable critic of dental amalgams and other dental therapies he believes to be harmful;[85] his views on amalgam toxicity were featured on 60 Minutes.
A 2003 monograph on mercury toxicity from the World Health Organization concluded that:
Studies on humans and animals have demonstrated that dental amalgam contributes significantly to mercury body burden in humans with amalgam fillings.
Dental amalgam is the most common form of exposure to elemental mercury in the general population, constituting a potentially significant source of exposure to elemental mercury, with estimates of daily intake from amalgam restorations ranging from 1 to 12.5 μg/day, the majority of dental amalgam holders being exposed to less than 5 μg mercury/day.
Intestinal absorption varies greatly among the various forms of mercury, with elemental mercury (as found in amalgam) being the least absorbed form (<0.01%)
Absorption also varies according to individual factors such as gum chewing and bruxism (tooth grinding).
The number of restorations - amalgam or otherwise - is declining, largely due to improved dental hygiene, in all industrialised countries examined declining by 38% since the 1970s in the USA and over 65% in the ten years from 1986 in the UK
Although several studies have demonstrated that some mercury from amalgam fillings is absorbed, no relationship was observed between the mercury release from amalgam fillings and the mercury concentration in basal brain.
However, in the same report it was concluded that "...even at very low mercury levels, subtle changes in visual system function can be measured."
In multiple sclerosis patients with amalgam fillings, red blood cells, haemoglobin, hematocrit, thyroxine (T4), T-lymphocytes and T-8 (CD8) suppressors cells levels are significantly lower, while blood urea nitrogen and hair mercury levels are significantly higher.
The report also notes that regarding elemental mercury exposure, the main form of exposure from dental amalgam," most studies rely on assessment of exposure at the time of study, which may not be fully informative, as mercury has a long half-life in the body and thus accumulates in continuous exposure ", making the evaluation of effects on health uncertain.
