Poems for a friend who has died include "Epitaph on a Friend" by Robert Burns, "By Herself and Her Friends" by Joyce Grenfell and "I'm Free" by Janice M. Fair-Salters. Chapter 3 of the Bible's Book of Ecclesiastics, titled "A Time for Everything," is also referenced as verse for bereavement.
It's often difficult to find the right words when one has lost a dear friend. Poems often offer sentiments that grieving loved ones may find difficult to formulate themselves. Poems like "Between the Clouds" by Gemma Lang put into words the overwhelming thoughts and feelings of tragically losing a friend.
Poems that insist individuals don't mourn deceased friends can also be useful. Verses like "Don't Stand at My Grave and Weep" by Mary Frye and "Don't Cry For Me" by an anonymous author encourage mourners to view their deceased loved ones as still with them.
"Do Not Go Gentle" by Neil Astley is a book of bereavement poetry that may be useful for individuals mourning a friend's death. While some compositions may be designed with the loss of specific types of people in mind, such as a mother or father, they may be applicable to the loss of a friend as well.
