2016 is a hungry beast...
I saw an interesting report on the news yesterday and a psychologist was analysing this very topic. She said it actually wasn't especially bad but social media has taken over helped us to release our own fears and angers about what is happening in the world today.
I suppose the political climate, wars etc are making people reach out and grieve on social media. So if you're a bad tempered, angry-at-the-world old git then keep grieving people you don't know! Ha ha ha.
