Are there any calming techniques?

Yes : A super easy way to calm down is to take about ten slow deep breaths. You want to be able to count to 5 slowly in your head as you breathe in and the same as you breathe out. You can imagine that you are letting all the anxiety out as you breathe out, and all the calm air in, as you breathe in. Aahhhh.

Stay active: Exercise is a great way to relieve stress. Your body releases endorphins during exercise, which can help you feel calm. If you exercise 30 - 60 minutes a day, your stress levels can improve. When stressed, take 5 slow, deep breaths with your eyes closed, then roll your shoulders forward 5 times, then back 5 times. This will slow your heart rate and release tension in your neck and shoulders.
