What This Means

Feeling jittery inside can be like being caught in a vice grip. Your heart races, your gut feels like it's flipping, and your jaw clenches tightly. It’s as if every muscle is on high alert.

This pattern exists because your body has an innate survival mechanism. When you feel threatened or unsafe, your nervous system goes into fight-or-flight mode. Your heart rate increases to pump more blood to muscles, your digestion slows down to conserve energy, and your muscles tense up for action.
