TW: health/cardiac symptoms

I have a family history of heart disease, and I’m really scared of falling victim to it myself. I’m in my 50s, and I’m being treated for high blood pressure, which doesn’t help. 

My anxiety manifest itself as physical symptoms - shortness of breath, mild chest pain, numbness in my left arm, etc. All are typical signs of a heart attack…and that’s immediately where my anxiety takes me. I also think my breathing is abnormal and either I’m slightly hyperventilating or I’m swallowing air. 

So, usually about 5 minutes into a panic attack, I start belching. I love it when that happens - that’s the point where I know in my gut “oh, this is just a panic attack.” It produces this wave of relief mentally and physically…and I know no matter how bad it seems, it’s (literally) all in my head. 

Just curious but does this happen with anyone else?
