Sad with you anon.
I lost a friend to Covid. He was in bad health to start, and wasn't much of a listener. But I didn't force the ivermec issue, and I regret that. I still don't know if he was on it.
What they don't tell you is that the damage comes not from the rona, but from the body's immune response. The fibrosis can occur after negative virus tests. So, imo, the key is to keep one's immune system calm through the fight, which, imo, means keeping one's spirit calm through the fight. Just me.
