My heart is racing at a highly normal pace. I checked my blood pressure, and even when I was nervous checking it it was on average 115/65. I'm 22 years old and have a stressful job, however I do not think I suffer from anxiety. The only real anxiety i have is over this racing heart. The more I think about it, the worse my heart races. The strange thing is when I work out in the morning doing heavy cardio I feel fine. It's only as the day goes on I feel worse and worse. I can actually feel my neck pulsing by my clavicles. I am slightly overweight but I am very active and live an active lifestyle. Please help, I'm a nervous wreck!
