I caused the death of an entire family

Well, I don't know where to begin, but let's get this over with. I'm a 21-year-old male who caused the death of an entire family. To understand what I mean, we need to go back to 2015 when ISIS controlled my country. I lived in an ordinary city; I spent most of my life there with a...My relatives and friends, and this is normal in my country, but when ISIS started to enter and control certain areas in my country, we weren't very afraid because those areas were far from us and we didn't expect this to happen to us, but it did. I remember The news was that they were approaching my city and that we should evacuate before they arrived, but they had already done so before we knew. My father and I went to the market to buy supplies for our trip and saw their vehicles driving by.My father told me to go home quickly and to do one specific thing before I went home: to tell our Christian neighbors to run away before they arrived. But I didn't. I was scared because of the news and the stories. I had been hearing about what ISIS was doing to their enemies, so I went straight home and told my family that ISIS had stormed the city. While we were waiting for my father to arrive, we started hearing the sounds of cars and gunfire, and I think you know what that means.It happened even though we left the city after a short time, and thank God my whole family is safe, but I still carry that guilt that if I had been a little braver I could have saved them note: I apologize for any errors in the English writing; it is not my native language.
