How does a person have enough positivity to actually choose to stay alive through things like this?

 This is obviously the 1 billion dollar question.

It is also why many people who are fundamentalists of all religions choose to believe in fairy tales rather than face the bleak truths in their lives worldwide. Simply because they don't want to be driven towards suicide or suicidal thoughts.

This is completely logical when you think about it.

Science in itself can be very suicide making when approached from the wrong angle to begin with.

So, people need to feed their spirits with good and hopeful news somehow while also believing in enough medical science to get vaccinated to keep themselves and their children alive through all of this. Because without the medical science aspect of all this many people are going to be maimed or killed by this pandemic.

And this is extremely unfortunate for those families who refuse vaccinations worldwide. It is also very unfortunate for countries on earth where vaccinations are not available at all.
