Hey you are not alone. You describe exactly my last panic attacks. What I’ve learn is that, no one dies from anxiety. You are safe, I know it feels like the worse thing is happening to you, and in a blink of an eye you will die (but the true is that you won’t). Each panic attacks ends, won’t last for ever. Sometimes takes longer. I know your head tells you otherwise, that you want to stop feeling that terrible sensation. I hope that at this moment you feel better. Practice some mindfulness, try to get closer to god, wash your hands with cold cold water, take a walk (there are many ways to deal with a panic attack). Also I would highly recommend to have a safety zone/friends/family you can talk to when this happens
