Heart, I did anything that would stop the cycling in my head. Exercise is so important because it stimulates and raises the feel good chemicals in our brains, counteracting excess cortisol production which can become a killer. I also played music really loud to drown out my thoughts.
I discovered that all the things addicts are taught to do to keep relapse at bay, apply to us as well. My therapist is an addictionologist and his feedback has been priceless. When we suggest to others to "work the program you wish they would" it's for so many reasons.
Hugs to you and prayers for your serenity
