Thanks for your feedback. Trouble is that candida is such a highly associative disease -- it's always associated with other pathogens so what you are dealing with is really a multi-pathogen disease whose symptoms can vary hugely. Most people think candida is like a simple bacteria or viral infection and that is quite a bad way to think about candida.
It might also be that you have other serious diseases like Lyme Disease whose symtpoms can be very similar to and may also involve candida.
Another reason for the seriousness and difficulty of your problem could also be due to Methylation issues. If you have aberrant or mutated genes triggered by missing vitamin or mineral enzyme cofactors in your Methylation Cylce then these can significantly bring down the immune system and detox pathways which can also affect the brain and blood. These issues are far too complex to discuss here but you can research Methylation Issues for yourself here.
