Sensitive to violent and negative images

Sometimes I hate watching scary movies, shows with violence, guns and etc. it freaks me out and stays in my head! I particularly hate watching the news because it gets me depressed about the cruel world we live in and just how sickening it is. All the violence just shakes me to the core..And I feel sorry for people..my heart is so big and my dreams make me think the world is perfect only to be reminded the world is cold and dangerous. But I’m trying to keep positive energy going.
