I lost my cousin in a drunk driving accident. One of the many reasons I quit drinking, couldn't manage to find a dd before I went out. It's so extremely hard to not want to blame yourself, but in all reality the only person responsible for driving drunk is the person doing it. My brother also lost two extremely close friends in drunk driving accidents. It's a terrible thing, but we can use it as a learning experience. I will pray for your friend and keep you in my thoughts.
