I am 20 years old, I experience heart palpitations on a daily basis, my ecg reports show a short PR interval. I have suffered from several panic attacks in the past 18 months. I tend to fidget a lot too. But fidgeting has reduced to some level now as compared to how it was 6 years ago. I get anxious a lot and tend to lose my temper. On some days I can not even get out of bed. I have a vitamin d deficiency (12.5/100) and a b12 deficiency too. My thyroid is perfectly fine. My muscles are always sore and tightened. I get lower back pain on walking or standing too much. On bad days its very difficult to even get out of my bed and go to college. Do I have anxiety? Some online tests have suggested so.
