a few months ago, my girlfriend went into cardiac arrest and was admitted into hospital, i was the one that gave her CPR after her ICD (Implantable Cardiac Defibrillator) failed. this left me with really traumatic anxiety and ever since, I’ve been having really really awful panic attacks everytime i have a heart palpitation or chest pain, this then turns into a spiral that i can’t get out of for days, “what if i do this and my heart gives up”, etc etc. and I’m sure it’s just anxiety because i never felt like this before this event, i know that all the signs point to it being just purely anxiety and i can tell myself that a million times, but it always turns into “but what if it’s not”, ive been getting dizzy when standing up and stretching and almost passing out from it at times too, i’m so terrified, i’m absolutely beside myself with fear, i don’t know what to do anymore.
