I'm the same.
I didn't click on the video you posted but have seen similar and am really struggling.
I was also crying in work and had to step outside.
Listening to colleagues chat about holidays and home improvements and thinking "how can this be real? How can this be fair?" Really puts things in perspective.
I'm struggling to get my head around it. What on earth is wrong with people?
Also struggling with the fact that there's nothing I can do to help. I've donated money, and will donate more when I can, but realistically, the kids that survive this....what is going to make things better for them? They've lost their families and their homes. Not to mention the ones who will have lifelong injuries and the poor souls who were killed.
I just despair of humanity.
