I'm sorry for your loss. When I was 13 years old I went through a similar experience. My grandad was murdered and my aunt and uncle were murder my grandma was shot. It was a random shooting the man was deranged and went to their homes in the night. When I woke up the next morning (having no idea there was a shooting) my dad woke us all up and took us to the hospital and told us grandma was having stomach surgery. We all were very confused but he said he would explain when we got to the hospital. We got to the waiting room and my mom broke the news to us. We all cried for hours and stayed at the hospital for months I was miserable. I didnt seem like it was real. It was all over every TV station for a few days and many articles were written. I shut down for a while. It's been 4 years and I still forget it all happened. This breaks my heart reading this since you must go through what I did. My only advice would be is to talk to family members and be close with them. They do love you and everyone is going through the shock of the death of very close family members. I'd also suggest counseling because I ended seeing one for around a year once a week. She helped me share my feelings and she helped me out of the shock that I had lost people I loved so quickly.
