Really nervous heart beating really fast horrible headache?

Anxiety : You could be having an anxiety attack , however , I highly suggest calling someone to take you to the ER or Urgent care for Evaluation . Have you had too much caffeine ? Have you taken any Meds or drugs you are not supposed to take ? Have you drank any substances you are not allowed at your age to have . Just to be on the safe side , get checked out ASAP

Stress : Your symptoms could be caused by stress. A change in your routine may be helpful
