LONG covid? COVID Pneumonia?

I got it last July. Like a summer cold for about 3 weeks. Was never really bad. But then I started suffering symptoms of myocarditis and made a couple trips to er because of the severity of the symptoms. Didn't feel normal for about 8 months but am back to walking 6 miles 4-5 days a week. I was vaxed because I have always had higher than normal bp. Runs in the family. Still not back to the level of fitness I had before.
