Has anyone gotten back to normal after one complication after another?

I’m 78 yr old female in good health. Able to swim 2 K and walk 1 mile 3 X week.
I tested positive for COVID on Feb. 10, 2023. I just had a cough - no other symptoms. Took a course of Paxlovid. After about a week, tested negative and was able to go back to short spurts of exercise - swimming and walking. After another week, noticed severe exercise intolerance. I’d get short of breath and my pulse would slow to 48 and become irregular. Saw cardiologist and EKG was essentially normal. Wore a 24 hr. Holter monitor which showed some irregularities but doc did not feel they were significant. In the meantime, chest congestion was getting worse so my internist put me on a course of prednisone. Then my blood pressure shot up to 210/110 and I landed in the ER. I was trending toward hypertension so I was put on Amlodipine. I’ve gotten my BP under control and have days when the shortness of breath is not too bad. (I use an Albuterol inhaler which helps). Then today (3/25) I woke up really lightheaded and had what I think was an anxiety attack. I was afraid I was going to die. I’m feeling better as the day goes on but still lightheaded. It’s just one thing after another. I wonder if I’m ever going to get back to normal.
I’m retired and don’t have to worry about work but my heart goes out to the younger ones who are experiencing similar post COVID symptoms and are unable to get back to work or a semblance of a normal life. I’m grateful to be able participate in this forum and read about other’s experiences and know that I’m not alone in all this. Thank you.
