Look at this it this way, if you dont pass you are still your current rank ;-P If you do pass great, just give it your best, knowing its all you can do. I also find Dan Jun Ho Bup to be helpful (deep breathing exercises) breath into your lower abdomen right below your navel in your nose, out your mouth...I have a grading on Friday for my blue belt, and I am very nervous. In my last class I felt like a lump, my back kick was shocking. :S
So, how do you guys deal with pre examination jitters?
I never got to the grading. On thursday night, while I was on a treadmil; my heart stopped.
For five minutes my heart stopped and started, and nothing I could do would fix it.
Then, I went to a doctor, who sent me to another, and another. Test after test, and they have no idea what it was.
They think it was a fribulation, and I'm getting a heart monitor when one becomes available.
I was forbidden to grade, and I think I'm not allowed to go to classes either. I'm only sixteen, and I never expected this to happen.
I just don't know what to do.
Irregular heartbeat is something that can happen to anyone. I strongly suggest discussing your concerns with your instructor, your doctor, your parents, and anyone else who might have reasonable input - your school guidance counselor, perhaps - although a lot is going to depend on what the medical tests show. It could be a valve irregularity (generally fixable); it could be a panic attack; it could be lots of things - until your doctor diagnoses it, and tells you what you can and can't do, please be careful!
Let us know what the doctor says - and remember, TKD will be there for you when you and your body are ready, and can be adapted if needed - but please don't put yourself in the way of potential harm to train - it'll be waiting when you're ready.
