My 17 year old son witnessed one of his close friends mown down by a car and killed last week, he was first on the scene and rang the ambulance etc. How do I help him through this ?. It is an important time of the year with AS level exams etc. He is devastated. has anyone else gone through this with their kids or have any advice please. I am going to contact his college to see if there is any counselling / help available.
