I'm sitting here on my couch, cat cuddled up on me, and my heart is pounding and i'm shaking for no reason. Like i'm literally just sitting here scrolling through reddit. I have low blood pressure and suspected POTS but i don't think its related to that. I have to go to work in 15 mins but it feels like my heart is going to burst out and i'm trembling. I find no reason as to why I get these episodes, no matter how hard i think about it. DAE??
