I feel for you Anon, and I can totally relate. This COVID is bullshit, and don't let it get between you and your dad. My mom had a UTI in a nursing home and they gave her a bunch of antibiotics to treat it, but all that did was weaken her system and she eventually died of another infection. After that ordeal, I've never trusted the medical system, and I certainly don't trust them now. I think most at that level you're dealing with mean well, and are nice people, but they are just regurgitating the same shit that the medical establishment tells them and taught them. It's too bad.
God is with you and your father.
