i had a panic attack a few days ago after smoking weed and was convinced it was a heart attack. i went to the er where they did an ekg and chest xray and said i was fine and it was just anxiety. i have been checking my pulse 50 - 60 times a day or more and bought a fitbit just to check it i dont know what to do, this is affecting my life and taking over and i hate it. what should i do?
