I have had all the vaccines for covid. In January of 2022 I got covid from my hubby. I ended up with extreme high BP (normally was low) in ICU. Very fatigued and in ICU for 6 days. Since then on high Bp meds. It has been very hard as like you I used to be very active. I am still very fatigued but little by little improving. Heart doc said high BP was related to covid. I also wanted to mention I also would het your thyroid checked to make sure your levels are o.k. Together we can get through this. This covid has been a hellish thing to deal with. Hugs and keep strong.
