Stressful in life...

I have been facing lots of events or situations that stresses me in life. I always recal when I was in highschool, every time we have tests I probably feel worry about it even when I'm already. My physical health affected by the stress like stomache, sweating. But I can cope with my anxiety right before the test starts. For example, I said the myself that " Thao, you studied for it so just take it easy or it maybe worse 'cuz you worry too much"
