The relaxation technique he used with me is to sit there and focus on the nailbed of one finger and slowly work my way up that finger and then to other fingers, up my hand, to my wrist, etc. I think I can do that without to much anxiety. He said I can start with any limb once I get good at it. He says I can even practice in small bits at work. Haven't tried that yet though.
I don't like the exercises where they have you close your eyes and visualize a quiet place, yadda yadda. Deep breathing isn't my cup of tea either, but t had me just slow my breathing. It wasn't too bad.
Talking about the reality of my own safety really helped. I don't have anything to be afraid of while I relax. I learned that a long time ago and those circumstances simply don't exist anymore.
