How do you deal with breathing anxiety and chest and back pain when breathing? It's been 7 Hours.

I have gotten maybe about 8 EKG’s within the lest 2 years? I’ve also gotten an echo done, and I got a heart monitor to track my heart over the course of maybe 2 weeks, back last year. Even though I have been to the emergency room so many times because of panic attacks that I thought were heart attacks, and went with a Cardiologist I still obsess and worry. I always think that I am going to develop some kind of heart problem after getting the tests done. Like if they’re just suddenly going to appear/my heart will suddenly have an issue. I especially get nervous when the pain is in the center of my chest + I get a tight feeling like I have pressure on my chest and can’t breathe completely. Please someone share their experience of how they controlled their health anxiety, especially if it’s related to this.

the anxiety is too much i can't keep still my chest hurts my heads full of thoughts im really struggling and don't know what else to do other than deep breathing and letting the anxiety be present

Just wondering if anyone else has shortness of breath caused by anxiety? I’ve been going through a really tough three months anxiety wise (POTS flareup; grief; migraines; panic attacks etc etc). Two days ago a new symptom appeared and it’s knocked me. Shortness of breath 😭 bc I’ve got POTS I’ve had a lot of heart tests done (multiple ECGS, 24 hour holter monitor) which all came back fine apart from the obvious tachycardia that comes with POTS. I had an echocardiogram done on Monday but no results back yet, but I had a consultation with my doctor yesterday and she said that’s probably good news bc they don’t mess around when it comes to your heart. And also my doctor has urgently referred me to a mental health team for therapy bc I basically broke down on the phone to her. One thing I’m mostly panicking about is this shortness of breath. I’ve had it with panic attacks before but this is mainly anxiety riddled feels like my breathing is too noticeable/wheezy without actually PHYSICALLY being wheezy. I’ve done my oxygen and it always stays between 97-99% so I know I’m getting enough oxygen but it does not feel that way and it’s so scary !! I also had a clear chest xray about ten months ago. Idk I feel like I’m just spending every day scanning my body because it feels OFF. Then I’ll finally relax JUST before I fall asleep and all my symptoms disappear. Then I wake up, have a nice 20 seconds before I start scanning again. It’s exhausting. Just looking for some support :(
