Acknowledge the reality that grief hurts. Work through the pain. Respect a person's need to grieve. Almost anything can trigger grief. Realize that grief causes difficulty in concentrating.
Teenagers often experience a shortened attention span.
School work is often affected. Maintain a daily routine if at all possible. Continuity becomes a safety net for grieving teenagers. The continuity of attending school daily, being required to perform certain tasks in and out of school and having a social routine provides teens with some security and sense of stability in a topsy-turvy world. Understand that people will continue to deal with the losses and changes they experience as they grow and mature.
