Linda, are you taking sublingual B12? B12 can help greatly with the mental and emotional state, as so many mercury toxic people are B12 deficient, and have trouble absorbing B12 supplements that are swallowed. Some even get B12 injections, although that is annoying, and can get expensive. There are also B12 patches, although few stores sell them. You could probably get them on the net. I have not tried them. Nasal B12 gel works pretty well, however it is hard to find now. I used it many years ago.
