Best of luck. I know of 2 old people that got it and recovered. They did however have headaches and fever for a few days but they did get through. Im hoping this is the same for you.
As for the idiots, im with you there as the argument i received the other day from, let me just call her Stupid, was that her friend runs 20kms a day so he cant possibly have covid even though his results were positive....
The blood, pressure thing. Get a blood pressure monitor, i personally went for sphygmomanometer and stethoscope but i do know how to use them. Stressing about it wont make it go down - it will have the opposite effect.
Try exercising more regularly (If you are not already) and making some better food choices for a week and see if you get results. It took me two weeks to get my pressure down slightly but I suspect its all stress and the reduced exercise.
It is the silent killer so start recording your BP daily, when you wake up and maybe before bed and have it checked out in a months time by a professional.
Ok so when I say high blood pressure I mean 120/80, cause that's fairly abnormal for me, like I pull 110/70, I did got get a BP meter today but I got the wrist one since the others were sold out, finally figured out how to operate it, bit clunky, and most of the day was 110/70, so I'm going to get a little active because I usually cycle and stuff but lock down has just been a giant shit fest of pacing the garden, and continue to just keep an eye on things.
