Hi, I am 29, male. Since last 3 months I am having shortness of breath, like I can't get a good deep breath, my GP and Cardiologist thinks its Anxiety as my ECG, Blood Tests, Chest X Ray, 2D Echo with Color Doppler and Stress Test all came back normal, so He put me on anti anxiety and anti depressant and anti biotics for Sinusitis (sinus x ray showed Sinusitis), BP is 130/80 to 120/80 with BP meds, recently I have noticed constant Rapid Heart Beat, is this all because of anxiety or what? I can't make mind calm, its just running with negative thoughts all the time
