More on anxiety

Anxiety inhibits problem solving.
​When you are worried, you are less likely to find positive solutions. 

If you CAN change something, problem solve and take action. 
If you can't change it, it isn't worth worry about. 

Close your eyes, inhale deeply and stiffen every muscle in your body like the tin man. 
Hold for 20 seconds. 
Then exhale and relax, become like the scarecrow with relaxed breath and body. 
Repeat this exercise.
Bring your focus back to your task at hand with a calmer mind and relaxed body.
