My naturopath feels that emotions such as these are tied completely to the liver; so your liver is ailing right now, likely due to the die-off toxins overloading your organs.
I would consider trying out acupuncture if the Ashwaganda doesn’t work. It can bring immediate relief and it’ll help you cope with the symptoms, etc.
If there’s a mineral hot springs near where you live, I highly recommend visiting it if at all possible; this will make you feel very good and help the body detox from candida. Other alternatives include doing a jacuzzi, steam room, hot tub, sauna, or even hot bath to help detox the toxins.
I had severe anxiety and mental symptoms before I started the diet and it only improved with time.
