@judijudimahoney these are all excellent grounding skills. As a retired behavioral health first responder, with a history of trauma and panic attacks myself, I would recommend you Google “ 4- square” breathing. This is easy to practice and can be done anywhere when you notice the symptoms of a panic response coming on. When we feel distressed, we stop breathing adequately and build up excess carbon monoxide. The mindful breathing is not only mentally grounding, but also restores oxygen balance and slows the increased heart rate that feels so scary! This 4-square breathing is taught to Navy Seals and I learned it years ago studying Isshinryu karate. It works! Hope this helps.
