Scared of Being Alone

I had a nightmare on Saturday, I dreamed that I lost my entire family in a tornado and I lived but I was so alone. I cried over their bodies and wish that they can come back. I was so alone and they were all gone. I'm used to being alone but alone without my family is like my heart being ripped out and I'm lying in a pool of my own blood. I wish that God didn't let this happened and wish that someone can help but all I can do is scream to the sky in pain, sorrow, and anger.
