A few weeks ago I felt my heart fluttering and beating irregularly which sent me into a cycle of panic attacks (which I havent had in a long time) and I ended up in the ER because I was severely afraid that something was wrong with my heart. They ran tests including EKGs and found nothing. Since then Ive seen two doctors who have both concluded that the palpitations and fluttering are all a side effect of stress and anxiety. I was lucky enough to get a few days off from work to rest and relax, but my anxiety and panic has yet to subside and I feel irrational and am convinced that Im going to have a heart attack or just die in my sleep for some reason. I havent felt like this in years and its miserable. The doctor I saw yesterday thankfully gave me something to calm me down so I feel normal right now and decided to post. Right before I start to panic my chest feels funny and my heart starts fluttering which then sends me into an overall panic that Im about to die and trying to sleep during this is next to impossible because Im terrified to be alone. Im wondering if anyone else has had bouts of panic that couldve been brought on by daily stress after not feeling anxiety for a long time. I had severe anxiety when I was younger and this seems to have just come out of nowhere and is making me worry that it wont go away, should I see a therapist? Also, what does your heart and chest feel like during an attack? Ive had no pain whatsoever, just the fluttering and palpitations which are still scary. Ive heard of relapses happening to people, could this be whats happening to me? Its been a pretty rough year for me and Im wondering if maybe this anxiety is my minds way of forcing me to deal with it. Any comments or suggestions are greatly appreciated, thank you.
