I’ve never really had a panic attack. I think I was heading for one once when I started thinking about being in a train IN A TUNNEL, UNDER WATER when I was on the Eurostar once - I’m a raging claustrophobe. I told myself, “Don’t be so bloody stupid!” and it didn’t come to anything. I watched something a few days ago and the guy picked three objects within sight (table, chair, picture) and kept repeating those to calm himself down. I saw something else where the person repeatedly counted their fingers. I suppose the trick is to get your mind onto something else, rather than thinking you can’t breath. I think I’d have something I know well on standby: something I know I can immediately go to rather than have to think about it. Like saying song lyrics or a poem or lines from a novel or something.
