Uh, the definition of sacrifice is :":the act of giving up something that you want to keep especially in order to get or do something else or to help someone."(merriam-webster dictionary)
You have pretty much described my life for more than a decade. It is not uncommon for me to be able to leave the house only a couple of times per month. That, by the way, is why I have the time to do so much more research than most people. I need the distraction. For me, getting back into shooting is an attempt to find an activity that makes it worth the pain to be upright and out of traction for a few hours. Believe me, there are a lot of times when death looks pretty damned attractive, so I am not "afraid" of Covid at all. I do care for the health and safety of other people, though, so when I do go out, I try my best to avoid being a part of the chain in the Covid death cycle.
None of that changes the fact that we do have some personal control over this particular disease. Nowhere near 100%, but some control. We are learning more about it every day and this leads to changes in advice from "experts". I know that's frustrating. What we do know is that this disease is usually not deliberately passed on by people who know they are infected and intend to infect others. It is done accidentally. I would imagine that most of you would say something like "if I had known I was contagious, I would have acted differently." That is part of the problem with this particular disease, most of the damage is done before its warning signs show up. The largest impact on this disease is done by people who take precautions even though they don't feel at personal risk.
I learned long ago that there are some people who will never change their minds, so there is little point in attempting to show them they are wrong. I bet everyone here knows someone like that. There are others who are aware that there is much incorrect information out there and would like to learn the truth or at least take a look at issues from a different angle. I am one of those people. That is why I participate in some of these discussions.
I honestly hope that none of you lose the ability to go about "normal lives" like I have, but because I spend much of my time immobile, I can offer do research for people who genuinely want to know details. I can't concentrate well all of the time, but when I can, just ask.
