I have anxiety. My main symptom is a racing heart rate well over 100 (my normal resting heart rate is around 75). Mentally, I always feel fine. I can think clearly and my thoughts are what I'd consider normal. So I don't think I have any mental reaction to my anxiety (unless it's just really subconscious and buried deep) but I do have physical ones. Aside from medication, how can I treat my anxiety for the physical symptoms if I don't even register the mental ones? I mostly ask because whenever I go to donate blood, 9/10 times, I get rejected cause of my pulse. My blood pressure and iron are fine. My pulse is just too high from my anxiety (and no, I'm not scared of needles or anything like that). Any advice would be greatly appreciated.
