I'm so very sorry you're going through this. You're right, a lot more people have Covid than statistics show, because most of us aren't reporting it.
I had a J&J vaccine and J&J booster, my husband had a J&J vaccine and Moderna booster, and we both got Covid in April.
We took a medicine that I can't mention on social media because the medicine is a pariah and I will be kicked off the platform for spreading misinformation. The narrative about Covid is carefully controlled.
But regardless of all this, I hope you recover soon. It's worrisome to me that ther are so many cases in the summer, when usually we experience better health. We are not going to avoid it. Many of my VACCINATED family members have already had it twice.
