When looking at the Periods of this artwork, how do you discuss its Auvers-sur-Oise's Emotional turmoil?
Emotional turmoil Illness had struck Theo's baby, Vincent, and Theo had health problems and employment issues. He was considering leaving his employer to start his own business.  Gachet, said to have his own eccentricities and neurosis, caused van Gogh to write: "Now when one blind man leads another blind man, don't they both end up in the ditch?"After visiting Paris for a family conference, Van Gogh returned to Auvers feeling more bleak.  In a letter he wrote, "And the prospect grows darker, I see no future at all."Wallace 1969, pp. 162–163 states, "But for all his appearance of a renewed well-being his life was very near its end." 
He later had a period where he said that "the trouble I had in my head has considerably calmed...I am completely absorbed in that immense plain covered with fields of wheat against the hills boundless as the sea in delicate colors of yellow and green, the pale violet of the plowed and weeded earth checkered at regular intervals with the green of the flowering potato plants, everything under a sky of delicate blue, white, pink, and violet. I am almost too calm, a state that is necessary to paint all that."
Four days after completing Wheat Fields after the Rain he shot himself in the Auvers wheat fields.  Van Gogh died on July 29, 1890.
