Mortality is a hard thing to get your head around. Try to not let it take over and keep doing the things you enjoy. Talk to some friends about it all. That should help get some perspectives. Don’t be afraid of going to sleep. Sleep is cozy and good for you.
If there is"no point" then the point is to do the most good and have the most fun whilst you can.
I work in healthcare and often talk to people and families about the dying process. We tell people that dying is a lot like falling asleep and that hearing is the last sense to go. So even if they aren’t awake and interacting anymore they are still aware of the people around them.
To me, dying is part of life, it’s the big unknown. Everyone dies, you can’t change that. What we can do is accept it and make the best life we can with the time we have. The point is enjoying the now. For me I focus on spending time with my wife and doing what good in the world I can do. I work with dying people a lot and if I can make even a few minutes of their time better I’ve made a difference that was worthwhile.
I don’t have any issues with them. What I do take issue with is companies enforcing them with the assumption being you will use your own mobile device to authenticate for them. I feel like it’s not worth the stink to complain but both places I work for require 2fa now and I need the authenticator app or get a message to my phone.
