George Bonanno, a professor of clinical psychology at Columbia University, conducted more than two decades of scientific studies on grief and trauma. Subjects of his studies number in the several thousand and include people who have suffered losses in the U.S. and cross-cultural studies in various countries around the world. His subjects suffered losses through war, terrorism, deaths of children, premature deaths of spouses, sexual abuse, childhood diagnoses of AIDS, and other potentially devastating loss events or potential trauma events.
In his book, The Other Side of Sadness: What the New Science of Bereavement Tells Us About Life After a Loss he summarizes his research. Because grief responses can take many forms, including laughter, celebration, and bawdiness, in addition to sadness. Bonanno coined the phrase "coping ugly" to describe the idea that some forms of coping may seem odd, bizarre, or yes, downright ugly. And you should know this: there is no right or wrong way to mourn a loss. There’s just your way.
