This is my first Reddit post, I just wanted to share my experience with cardiophobia and anxiety in general, as I am writing this is am going through one right now, thinking this will help get it out of my mind.

I like to read and learn some new stuff but turns out this was not helpful at all. had my first panic attack about a year ago when I was scratched by a cat, thinking I was about to die of rabies, I made myself believe that I was having a headache and I had a fever, thinking that my time was about to end. I physically could not stop myself from googling how could i have gotten rabies in the first place, but then I called my neighbor to make him check if the cat was okay and not dead, he reassured me, and my panic attacks and all of my symptoms went gone away. 

but recently I guess due to stress my anxiety about my heart health began. I would say I am pretty healthy, I go to the gym often, I am in a good shape and I am 20 years old, so having a heart attack at this age would be highly unlikely but it's just like my brain is whole other person who is trying to make me believe that I might be that unlucky one. around 3-4 weeks ago I had a panic attack, my heart was going crazy I could not calm down, I took some medication and even that could no help me, I tried to watch some movies but that made it worse, I felt like my heart was getting weaker and was about to stop so the next day I went to a doctor to get it checked out, got a cardiogram and doctor just told me to laugh it off and said it was due to stress and needed to take some time off work. so that was it, for now, occasionally I would get a fast heartbeat but I could brush it off. so I took a vacation away from my city to just relax, but oh boy that's where it all went bad, it was just a random night when I felt pain in my chest, I thought nothing of it and tried to brush it off, but my brain just got paranoid and made me search my symptoms and all of a sudden my symptoms got a lot worse, my chest got tight I felt nauseous tired and weak, I felt like lost control of my body, so I had left my vacation just to go to the hospital and get it checked out again but just as soon as I went in the hospital every symptom went away, I talked to my doctor and she prescribed my some anti-depressants which I am currently on right now. but I am experiencing all of the symptoms again, my chest hurts, my back is tight and I feel like something is stuck in my throat, I just can't calm down, I am planning to go to my doctor again to get a stress test and bloodwork done and after that talk to a professional therapist. (Reading all of your guys stories helped me calm down a lot) 

Everyone reading this and going through this it will get better &lt;3

I'll update you when I get back
