This has definitely happened to me, I know it can be scary. If I'm at work then I'll go to the bathroom for a few minutes and take deep breathes, or if I'm at home I'll listen to music or watch funny YouTube videos to take my mind off the anxiety, and if you like drawing (like I do), that's a healthy way to express yourself! I hope this helps and that you feel better!

I have had this before. I’ll usually lay cold packs on my chest to calm down when the anxiety is worse or a heating pad if the pain is worse. Both of these have helped me. But if you can’t handle that sensory-wise, try taking deep breaths through your stomach and try to relax your muscles as much as possible. I’m not sure if it will help your anxiety, but it should help the physical aspect
