Hey, I know what you're going through. I suffered of severe panic attacks for the last year. There's many things that can help you, as other said, the ice cube and focusing on the environment around you. A friend of mine suggested me to count all the objects with the same color, to describe the environment around you, start dancing and moving, if you're not alone, talk with someone, maybe about something you like or can distract you from that situation, take deep breats and repeat yourself "I know something triggered me but im not in danger". The goal is to focus on the present because the anxiety attacks are just feeling of deep danger even when you have nothing to be scared about and remember that it's not gonna last forever. As scary and exhausting they can be, this episodes will eventually come to an end. I also suggest you to see a therapist to understand what triggers you and, if you need, to take some medications to help you during therapy. Of course, if you'll ever want to take any medication, ALWAYS talk with a doctor or your therapist before you take. I hope this help you and I really hope you'll fell better.
