Everything changes when your dad is killed. My sense of security is now gone. The sick-to-your-stomach feeling you get when you hear your friends talking about spending time with their dad. The pain you feel when you realize you start to talk about your dad in past tense. The anxiety and panic you feel when someone doesn’t call you when they say they will, or they are running late. The sickening feeling you get when you drive past where he was killed. Everything changes.
