Amy, I try to focus on gratitude and use breathing techniques. (Thank you Mindfulness in Medicine!) Long walks and a good nap can work wonders too.

As for dealing with teenagers, I'm still working on adding more techniques to my toolkit. Over and over in my head, I recite, "Do not engage! Do not engage! Do not engage!" and remind myself of all the reasons he is loved so much, and that this is just part of learning and growing. These traits will develop and serve him well as an adult.
