Hey, Jon. Thanks for your welcome to this forum on my thread. You live just west of me a bit (I'm a fellow Texan). I have several friends who run White Rock each year. It's a great course.
I'm sorry to hear you were served, but glad you survived. One day at a time, one moment at a time. As Michelle suggested....deep breath. I know firsthand how even breathing can sometimes physically hurt, but you will get through it.
I've been reading a book called "Journey from Abandonment to Healing." It's been helpful to me as I'm trying to begin recovery from this nightmare and get my feet back on solid ground. The exercise you are doing is so very good for mind and body. Keep taking care of yourself.
