Stress symptoms vary greatly from one person to the next, but the most universal sign of stress is a feeling of being pressured or overwhelmed.
Other symptoms include:
Physical complaints (stomachaches, headaches, chest pains, nausea, and diarrhea, and a sensation of numbness or tingling in your hands, arms, and face.)
Problems getting along with family members, friends, and teachers.
Changes in behavior at home (short temper, unexplained anger, crying for no reason).
Regression -- behavior that is not age-appropriate.
Dysfunctional sleep patterns, including nightmares, too little sleep, difficulty falling asleep, or even oversleeping.
Communication difficulty or personality changes, such as becoming withdrawn or requiring much more attention than usual.
Impatience.
