Those who struggle with anxiety make too much fast-processing speed called High Beta. When you live in high High Beta you can feel anxiousness, irritability, or overwhelm, you react instead of respond and need something to calm your brain.
Think of it as a road. When the brain is using an anxiety pattern, it is off course, or "off-roading.” And according to Hebb’s Law, the brain is memorizing that off-road course.
