What is going on?

I don't understand what's going on, either with the riots or with myself.
What are we as humans doing to allow / make this happen? Disspiriting and depressing. Heart is hurting pathetically for those that have been made homeless, have died or been injured, lost livelihoods and got caught up in something that they didn't want to be involved in. Humanity can be good, but just now, this, this is frightening.

Overwhelmed, bombarded, hopeless, shattered, hurt, worried, powerless. 
It is often a whimsical thought - that I want to escape the world, or stop it and to get off...
