As with people of all ages, past experiences and emotional development greatly influence a teen's concept of death. Most teens understand that death is permanent, and that everyone dies. Some may have experienced the death of a family member, friend, or pet.
Teens, like adults, may want to have their religious or cultural rituals observed.
Most teens are starting to establish their identity, independence, and relation to peers. A main theme in teens is feeling immortal or being exempt from death. Their realization of their own death threatens all of these ideas. Denial and defiant attitudes may suddenly change the personality of a teen facing death. Teens may feel they no longer belong or fit in with their peers. They may also feel that they can't talk with their parents.
Self-image is also important to teens. A terminal illness or the effects of treatment may cause many difficult physical changes. Teens may feel alone in their struggle, and scared, and angry.
It's important for parents to realize that children of all ages respond to death in unique ways. Children need support. They need someone who will listen to them, reassure them, and ease their fears.
