See the control you have and experience as you do this. Close you eyes and visualize clear breath moving through your body. Don't be attached to the outcome. Continue with your efforts, and know that they are the right things for you to do at the moment, but surrender any attachment you have as to the outcome. It's the attachment to outcome, to things being a certain way, that brings us pain.
Peace comes with letting go, surrendering, and acceptance.
It also makes us more open to learning from our experience, instead of resisting it. I used every one of them during a recent stressful time I was having. It didn't work. I had to resort to other measures and after suffering emotional distress almost all day, I finally let go and did every one of the things above. I felt a bit better.
