For me, mercury and anxiety/depression go hand in hand. Both symptoms are often the most common in many patients out of any others. Mercury is notorius for causing these behaviours and an expert doctor in US on the matter spoke to her audience of doctors about these kinds of patients and the anxiety that goes with it, including the depression.

For me, mercury caused such horrible nervousness/anxiety, that I would shake. I think it does this by acting on the brain/nervous system and adrenal glands. My pupils were permanetly enlarged, I was hyped up, frightened of anything. One of the symptoms of mercury is fearfulness, inexplicable fears and for me this was a biggy. I had uncontrollable giggling fits and that with the large pupils, was often accused of being on drugs. Not surprised, but no I certainly was not. I was definitely a mad hatter many times.

Sosick, I'm amazed you never experienced that! But then again, mercury does different things to different people, so I guess it's a real individual thing and people often find some symptoms i have had too strange and could not really relate to them (uncontrollable crying and salivating fits and the giggling spells). Interesting enough, the giggling would often occur after I had drunk a hot drink (even hot water), which would increase the vapor uptake from the fillings I assume and I would even get wheezing along with it. I got similar from hot baths as the toxin would come out of my pores and i'd breath some of it in and the giggling would start and I found that hard to handle at times, especially when this can happen in front of other people and I'd have to get up and leave the room. Quite amazing symptoms.

For me it also caused extreme feelings of rage, so bad I would feel afraid of myself and what I could do. Suicidal depression etc, the list goes on.

Mercury out of just about anything seems to cause the most bizzare symptoms I've ever experienced or heard about.
