Sad things

I wanted to cry so I looked at sad things. Now I haven't cried but I read about the Bosnian war and the children dying, the victims of the Sandy Hook school shooting the twins a boy and a girl the boy died and the sister lived, a 3 year old boy that found a gun on his 3rd birthday and shot himself in the chest with it, and 8 year old Martin Richard, the boy killed in the Boston Marathon Bombing. How his mother stayed by his side while his father went to save their daughter. She lost her left leg. Martin had his left arm almost completely blown off, a 6x6 inch hole in his abdomen exposing his intestines, his left leg was cut to pieces, his pants melted to his body, and covered in 3rd degree burns. He didn't die instantly, he was alive. In pain, he died reaching for his mother. I think he died a few seconds after the second blast. Even if he only lived for 20 seconds like that it's still just depressing. He felt the pain. It's all just so sad and I can't get any of it off my mind.
