Indeed! Candida and parasite cause severe depression. My brain fog is much better now. I found that a herb:sage is highly helpful. At some point my nervous system would be so much in need, that my hands' movement would not even be coordinated and I would be clumsy as never. Since I have found out about sage (the right name for this herb aint it?) I am getting much better escept for the anxiety.... but anxiety can only be helped with vitamin B and too much vitamin B will feed candida in return.
