Keeping blood pressure low.

Leigh
I have a problem! I'm a coach and Pe teacher. At my elementary school where I teach Pe it is really challenging. We are a very low income area, I love my kids but they can be very challenging. Yesterday I had to break up a fight between a boy and a girl.  I feel like My blood pressure spikes about 4 times a day!!! Does anyone have any suggestions of what I can do to keep my blood pressure down during high stress times. I'm 8 weeks along.
