There's a site I like a lot, I get updates from them on Facebook, called Upworthy. They've gotten quite popular on FB and Twitter, so maybe you already know about them. Anyway, this video has been going around for a couple of days. I finally watched it today and... it is very powerful. And painful. And wonderful.
It's a spoken word poem performed by the author and illustrated by many. Please watch
Also, here's more information on the poet and poem via his website and Facebook page.
