I was recently chatting with a psychiatrist about the creative process, specifically among poets. He admitted that he doesn’t know much about poetry, but I was nevertheless surprised to learn that he believed the stereotype of the poet who works most creatively when depressed.
“You deal with depressed people all the time,” I said. “Do they strike you as particularly motivated to do anything creative?”
He admitted that one hallmark of depression is loss of motivation–to do anything, let alone create expressive art of any kind. So it would follow, I suggested, that a period in which a person is seriously working at what he or she loves would be unlikely to coincide with a full-blown depressive episode.
“What about those poets who write about, say, staring out a window and sadness,” he asked, “They seem to write about being depressed, to express the feelings of depression.”
True, some poets experience depression (some commit suicide, too); and some express those feelings in verse. Yet none of the working writers I know who struggle with forms of depression write while in the midst of the “black mood.” They can only write well when the mood has not seized them fully; and while they may try to convey those feelings of the ‘inexpressible,’ they write and especially, revise, the work during more productive hours when melancholia has tapered a bit.

It takes concentration, creativity, and analysis to craft a poem that adequately means what depression feels like. You cannot access such things when you are truly depressed. Some writers want to portray the experience; others want to explain it; still others prefer to write about the desire to escape, or even to embrace, the melancholy; others simply relate what they observe. Trying to pigeonhole all writers who address despair defies reason and suggests that all writers undergo the same feelings and experiences. Excuse me, we are individuals–diversely, wildly, enthusiastically unique.
That said, I cannot make the claim that no one has ever created a great work of art or poem while in the midst of a clinical depression; I merely posit that it’s likely that poetry composed while the author is gripped by existential melancholy will not meet the poet’s own standards.
Lewis Wolpert, a biologist and author, says, “I claim that if you can truly describe what it is like, then you have not had a true depression. It’s an illusion, and completely unlike anything else. When you are immersed in it, you enter a world without reference points, so once you recover it is very hard to relate how you felt.”
A world without reference points–that is the attraction depression might hold for a writer: the creative summons to relate an experience that is essentially beyond description. But most writers are not able to answer that summons while in the depths themselves.
And many writers are not troubled by depression at all. [See this 2012 article from the UK’s Mental Health Foundation for essential insight and clarification of an earlier study–that abstract is here.] The studies do suggest that writers are more likely than the general population to have bipolar disorder, which makes a kind of sense to me: after the sinkhole of a depressive period, the active “manic” phase might permit a writer to accomplish a great deal, including possibly a description of the void. Or it might not.
At any rate, I hope that people–psychiatrists, for example!–eventually recognize that we should not stereotype artists and poets any more than we should stereotype people who have mental illnesses, different accents, or skin color that is dissimilar to our own. What makes artists “different from other people” remains a mystery despite years of research and speculation, and my gut feeling is that the difference has more to do with other aspects of the creative process than it does with depression of any stripe.
