What is your detox protocol?
If you are not detoxing the toxins from the dead candida, then they will recirculate in the body causing damage to a variety of organs including your brain. If it damages your brain then you get anxiety. Fatty acids likely will help prevent the anxiety and a good one to try out is flax oil.
Lamisil is a prescription antifungal product and you need to detox from it imho.
