@brit CPR is cardio pulmonary rescuscitation that is done when someone's heart function and breathing stops to save a person. PTSD is post traumatic stress disorder that happens after a frightening event which tends to cause panic attacks. PTSD is hard to live with and disrupts your life when events trigger memories of the very traumatic events that happened in the past. PTSD is treatable. I experienced some of that with extreme fears of having surgery because of fearful similar experiences when I was little. Every time I thought about having spine surgery, I panicked. Some of that was also because of the injury I had in a car accident twenty tears earlier, that caused the spine problem I had that then needed surgery, and that accident was also a traumatic event contributing to the problem..
