I think we can indeed blame unnatural anxiety and withdrawn feelings on mercury and illness if in fact we know that it came from that as a result.

Mercury is notorious for causing hermit like behaviour and other illnesses and toxicities can also interfere easily with the normal feelings/chemicals in the mind and cause a normally happy outgoing to withdraw and become depressed or anxious when they would not normally do so. It's happened to me and I"ve seen it happen to others.

When people are truly well, they naturally respond accordingly and going out and socialising become something one starts to naturally desire again. I've had momentary feelings of it . I just can't help wanting to leave the house. The world or people no longer seem "scary" or bother me, in fact I seek them out.

When I am ill, which is most of the time, I withdraw and feel nervous. even animals can respond the same way....

People in pretty normal to "ok" health, or don't suffer these types of sicknesses usually have none of these kinds of issues. Yet they are typical in those with toxicity.
