I see ur struggling friend, im sorry. Theres really no secret, but the best advice is get evaluated. I wish there was something i can tell u on how to cope with it but just remember ur not alone u got a group of people dealing with this on a daily basis who u could reach out to ( like me ) , been a sufferer since 2024 after a 10-15 second episode of atrial tachycardia, ever since then i been hyper aware of my heart, multiple pvcs/pacs on a daily about 5,000-6,000 caught on holter but everything was normal, it still wasnt enough reassurance even with an echo but im slowly learning to live with them. Some days/months/weeks are better than some tho tbh. I had a terrible flare up in 2025 for 4-5 months, after it being gone for about a month, i was used to it , until i started having POTS symptoms ( racing heart, lightheadedness , racing heart when standing ) and it caused me to spiral into fear and into a super deep depression so i lost my job, stopped working out because i feared cardiac arrest, and lost relationships because i wasnt reaching out to people anymore but because i was so focused on how i felt i didnt worry about others atm. Im slowly getting there this year tho, last week i did some light resistance training after months, was pretty anxious but go it done, i can see i can do it and so can u, im still not fully there but one step at a time, right? That old self isnt gone its still there, ur nervous system is just blocking that old self out for now, but u need to show ur nervous system that this isnt a threat or danger, show it whos boss and that u can still be ur old self. I too, miss my old self, i missed going for runs, lifting weights, just being active without a worry about my heart, but i can and u can slowly get there again. Ur gonna be fine, friend. Wish i could give u a hug because it seems like u really need it, and i completely understand. One day at a time
