In last year i had many ecg test, echocardiogram, blood tests.. always all came up as good, no problems with my heart.. had chest xray etc.. always all good and still i have daily terrible fear that something can happen. Last time i visited a doctor just 4 days ago with fear that i could have a blood clot in my lungs... of course i did not. Got another ecg, blood tests.. again all ok. I have often fast heartbeating, got a beta blockers for it.. they said is nothing to worry about. All this started year ago when i got some big pain to chest and as they said in hospital.. my first panic attack.. from the day i live in fear... when my heart beats a bit stronger after some walk, or stand up from bed etc.. i got terrible anxiety something is wrong. I am able to go to hospital and say i got chest pain just to get my heart checked.. I am feeling like a mad already.. Just cant stop to have the fear that even all tests were good few days or few months ago.. today can something happen to my heart... My life is hell now..
