A tip for relieving stress in the moment of a "stress crisis" try deep breathing.
I took this from an article from SparkPeople.com:
"Deep breathing, an easy and convenient way to relax, it is the core of many other relaxation techniques. You can practice deep breathing anywhere. Simply take ten deep breaths, lifting your chest to fill your lungs completely and then exhaling all the way. Each breath will relax your body a little bit more and you will feel the tension seep out of your muscles"
"And peace that passes all understanding will guard your hearts and minds in Christ Jesus." Philippians 4:7
