Hello,I am 29 years old male, 5 7, 140 lbs, from last two months i am suffering from a fear of sudden cardiac arrest without any valid reason, i did several appointments with doctor and undergone ecg, echo, ETT, holter monitor test and all the results came normal, i have no family history of heart disease also, i have read the causes of sca and i know that i am not at risk of sca. Basically I have read many article in the internet about sca which made my anxiety worse. What should i do now... this fear has made my life hell !! In some of the article they told that sca can occur to completely healthy person also... after reading this i cant live my life to the fullest... i am in fear and huge depression( i dont smoke and also carry out regular physical activities)... please help me how can i get rid of this anxiety?
