This take is sad. We have become a society of emotionally weak people.
My wife and I make our kids do uncomfortable things because that’s what separates children from adults. An example, and not even the hardest one: Yesterday we were vacationing at the beach and we got a call from the dog boarding facility keeping our 8 year old dog, she was having seizures and had to be taken to an animal hospital. We drove 3 hours to see her. There was lots of crying, in front of everyone - who gives a shit. We had to have her euthanized. The 4 of us stayed with her for the entire process. We could have just told them to put her down over the phone and continued our vacation, or we could have left the room as they ended her life. She wasn’t conscious and we have no way of knowing if she was aware of our presence, but if something/someone makes an impact on your life, learn to be a little unselfish and be present. It hurts, but just because something hurts doesn’t mean we should shy away from doing it.
Learning to steel yourself is an important life skill. Obviously a dog is not a human, but the parallels are there - as humans we have honored the end of a impactful life throughout our history.
It's also selfish, narcissistic and kind of anti-social. Somehow, we've uplifted "taking care of yourself" over every other societal norm, obligation, and courtesy. Humans are not meant to be "on the comfortable/happy path" 100% of the time. Sometimes, we are expected to act altruistically. Sometimes we should make small sacrifices for others' benefits. Sometimes we should be go out of our comfort zone to comfort someone else. This doesn't mean torture yourself and ruin your mental health, but it does mean stepping out of your usual routine occasionally, for other people's sake.
