LONG covid? COVID Pneumonia?

I got it when it 1st came out. Symptoms lasted about three days. I didn't get vaccinated figuring I had Immunity. Then in August I got Delta variant. Almost died. My first night in the hospital my heart rate went to 300 BPM ! Could barely breathe. Took about 30 minutes to stabilize me and was transferred. I refused incubation and finally got sent home after about three loooonnngggg weeks where I spent the next three months at home on oxygen. Struggled with shortness of breath for about another six months after that. Fun times! Oh Yeah, they treated me like **** in the hospital because I wasn't vaccinated but that's a story in itself. Luckily the strains are less intense now. I did get vaccinated after all that not that I wanted to but didn't want to take a chance.Also the only gave me oxygen and regular antibiotics. I'm sure treatments are much better now.
