Hey, I'm sorry you're getting these - I used to get them often and they're awful. I'm not a health professional, but here's what worked for me. Not OP by the way.

For the short-term, try meditation/breathing exercises, physical activity (walking, running, push-ups, etc.), and honestly calling someone to talk about it. Writing out what I was feeling helped too, since I'd find myself ruminating. I'm not sure what your anxiety is fixed on, but I felt like I was going to die of some health event. It was completely irrational. It's hard to remember in the moment, but it's true. You will be ok, and this won't last forever. Your body cannot keep you panicking for long, and eventually you will tire (even though it feels like forever sometimes).

For mid/long-term treatment, I seriously recommend considering therapy and medication. Daily medication has made my life so much more manageable, and panic attacks almost never happen now (some medications are taken as needed and work quickly in case of panic, some you take daily and work over time). Meditation, physical fitness, and trying to work on nutrition have also been really beneficial for me and I can't recommend them enough.

Just one more comment: I'm alcoholic - drinking was a big source of anxiety for me as well (hangovers, spending habits, etc.). Since working on sobriety I've felt an enormous drop in anxiety and a much better ability to manage the anxiety that arises. I'm not saying this is the case for you at all, just that it's helpful to notice the psychoactive substances you take (if any) and assess their place in your life.

Best of luck and message me any time. You can get through this.
