What I do when I'm over stressed:

1: I relax by taking a deep breath and meditate:  This helps to calm my nerves.

2: I get enough sleep: I don't joke with sleep. did you know most headaches are due to stress. Lack of sleep can cause stress and anxiety. Aim at 7-8 hours sleep per night.

3: I exercise: it makes me feel relaxed and energized. Aim for at least 30 minutes exercise 3 times a week.

4: I don't over commit myself to work. I prioritize my  time. I must not complete all task a day.
