i agree, I think the pains of mercury poisoning are some of the hardest that anyone can go through in their life time, it penetrates right to your core distorts everything in your mind, leaving u with paranoid delusions and constant negative thoughts. I also developed thought patterns and emotions that seemed to be not of this world, they were that bad.

I know the pain of losing a loved one or finding out you have cancer and being treated for it are extremely difficult also, but I think that pain mercury instills is right up there when compared to them
