I have a constant fear that I’m going to have cardiac arrest or a fatal arrhythmia.. I (26F; in good health) just got back from the gym and it was GREAT. Now I’m in my car about to get lunch and BAM. My anxiety kicked in and my heart started beating soo fast (honestly it probs only beating 100bpm) and all I can think about is what if I die from a cardiac event.. I’m on beta blockers literally for my anxiety and am in therapy, but sometimes these thoughts happen from time to time and it’s frustrating… I have no real problems with my heart and it’s all in my head but sometimes I just wish it would turn off :,)
