Long story short, I had a massive anxiety attack 2 months ago after smoking some pot. Had anxiety attacks every day after that. Started to experience chest pains, heart palpitations, racing heart beat, shortness of breathing on a regular basis. Went to the doctor, they set up an echocardiogram and a holter monitor test. Echo came back fine, still waiting for holter results. Went to the ER one night because I was convinced I was having a heart attack. ECG, Chest X-ray, blood tests all came back fine. They diagnosed me with anxiety and gave me some lorazepam for when I have an attack. I'm starting to see a therapist now.
For some reason I am still convinced that I have a heart problem even though all the tests came back negative. I was just lying down watching some TV today, and my heart rate started going (120 BPM at rest what?!) so I took some lorazepam, took a shower, did some breathing and its starting to go back. But I just get so uncomfortable when I am just lying there and I feel my heart racing pounding for no reason! I feel like I can't deal with it. Why can I not seem to just calm down and convince myself that I'm not dying!? Nothing seems to work.
