7/11 breathing. A skill to use for anxiety. It’s recommended to do it for 10-15 minutes. Like any other skill it does require a lot of practice. I advice that you practice it when you are feeling calm so you are ready in a time of need. If you lose count, which is easily done, simply start again until you do 15 minutes. It will also help with distraction even if you don’t get it right the first hundred times.
