I had all of those symptoms you describe for almost a month. Racing heart, short of breath and high BP. My BP was 140/95, I was sweating profusely just doing household tasks. Anxiety was through the roof. Every night going to bed I wondered if I would wake up.
I am still having shortness of breath on and off at day 51 but my BP is back to normal and the sweating has stopped. It seemed to improve after about 35 days. I too will have to follow up with a doctor (I am terrified). I wish you luck and hope things improve for you soon.
