I have panic attacks once my anxiety gets so high. Last night was the worst of my life. I was hyperventilating for prob 2 minutes but it felt closer to 5. Luckily, I was reviewing some articles about CPTSD yesterday and I can’t find it now, but it read that drinking water helps because it activates the salivary glands which causes the brain to refocus, I believe to the frontal cortex. My husband walked in on me and was able to help me get to the sink. Idk how long it would have went on for if I had not read that.
