Breathing exercises: You can start by doing breathing exercises. Sit comfortably in a quiet place, close your eyes and focus on your breathing. Take slow, deep and full breaths, feel the air going into your lungs and coming out of your nose. Feel your stomach filling up with each breath and try to make your stomach go in and out with each breath. This technique will help you gain control of your anxiety.

Reassurance: If this isn't usual for you, consider a physical exam and treatment if needed. Also, pay attention to healthy diet, sleep, exercise, etc. Seek feedback from trusted teachers on your probable readiness and suggestions for improvement. Try to believe that a setback is just that - not a disaster. If you are need more time - you do. At 16, even if it's hard to believe, you have lots. You'll catch up!

Exercise!! : Exercise, especially cardio activities that get your heart rate up, are great for both managing stress and optimizing brain function. Good luck!

A "Worry Script": You might want to try writing a "worry script": essentially, pick one of your worries ; write about the worst thing that could happen if that thing were to actually happen. Many people don't like to think about their worries coming true even though they know that thinking about something doesn't make it so ; that a thought can't hurt them.
