More advice on how to eliminate your worries:
Shift away from out-of-control thoughts. Get into the present, take action, and focus on what you want. A student concerned about exams should stay present, prepare, and focus on great results.
Anxiety is often caused by inaction. Physically preparing or mentally shifting gears can move you to a higher plateau of strength, confidence, and trust. This is where you are fully capable and open to the resources available that make the very best of a situation.
