I also experienced anxiety in general when I was very ill. I had a short temper, I was snappy, and I couldn’t handle stress very well at all. When I went through the first 2 weeks of die-off, I felt like one of those little chihuahas (dog) and I felt all skittish, I felt like barking at everyone, and I just could not chill out easily.
In general your body is under a lot of stress because of all of the toxins being released and this effects your psychology as well.
I generally “tripped out” when I went through die-off and thought people were talking to me all of the time when they were not. I experienced hot flashes like I was wearing winter clothing and running, sweats, the “burn/itch”, etc.
Another way of looking it at is that your body is used to a drug out there called sugar. Sugar should be classified as a drug in my opinion and stopping it can cause withdrawal symptoms and all sorts of unusual stuff.
