Agreed. I had an experience a few months ago when I was absolutely at a very low point, and somebody who knew very well I was very low did/said some extremely cruel things to/about me for the sheer sake of being cruel and hurting me.
When I heard about this this morning, I thought about my situation. I'm not saying I was suicidal, but what if what that person did to me sent me over the edge, since I was already EXTREMELY vulnerable and depressed? How would he have felt had I gone and done something drastic to hurt myself because it was just the last straw?
You never know what battle another person is fighting or what demons they have going-on in their head. It's so sad.
