Robert Lowell's Skunk Hour - a lonely, dark poem

Robert Lowell's poignant poem Skunk Hour seems to revolve around the plaintive line near the center of the poem: My mind's not right - this line, sadly , made especially memorable because of what we know of Lowell and his lifelong battle with mental illness (depression, or bipolar disorder?), the wages of being a confessional poet and displaying your life as on a screen. This poem is a short and slicing portrait of a small village on a New England coastal island - referred to here as Nautilus Island, but not sure if that's a real place: seems to be like one of the Elizabeth Islands (which would explain his odd choice to refer to Queen Victoria's century). The poem is one of decay and dissolution, a brief catalogue of the things - like the poet's mind - that are "not right" : the hermit woman "in her dotage" who buys buildings and "lets them fall" to preserve her view; the "summer millionaire" who left and had his yawl "auctioned off to lobstermen." The bastions of New England village life are now a wreckage: which leads the poet to some real wreckage - he drives off, alone presumably, to survey the town from a hill, listening to (or overhearing?) a C&W song, Careless Love - but he's alone, unloved, and perhaps suicidal - as he looks at the "love-cars" parked near one another he feels especially desperate - that's when he declares that his mind is "not right." But something lives in this dying place - the skunks, marching up Main Street, it's almost a nightmare vision - but also in a weird way reaffirming, he sees at the end a mother skunk with her "kittens," digging in the garbage, unafraid of him. So what to make of this? It's a poem that seems to move across the island, to different points of view - the first part across water, the second from the top of a hill at night, the third from the poet's back steps - he's a wanderer, searching for some sign of life, or of companionship - but there are no relations in this poem. The people he describes - the hermit, the millionaire, the "fairy" - are all isolate, and so is the poet: all that lives together are the family of skunks. Notably, he references Satan in Paradise Lost: I myself am hell. It's the isolation of someone fighting for his sanity, and finding no solace in the world, and its beauty, that surrounds him - he's dismissive of the beauty and unengaged with people - a lonely, dark poem. The teetering rhyme scheme - most of the stanzas contain one rhymed pair, but randomly placed - adds to the mood of uneasiness and uncertainty in the poem - the sense of order is hinted at but just out of reach, as each stanza hints at a pattern the breaks apart.
