And if the implication is somewhat tinged with "lack of success leads to unhappiness," Hemingway's father blew his own brains out, so it's less that Hemingway was unhappy with his literary results and more genetically predisposed to shooting his head off.
(Hemingway was, also, definitionally a commercial writer, as he was literally a war correspondent. I.e., someone writing serves commerce.)
Hemingway committed suicide after having his brain fried with repeated ECT sessions (and back then, it was far more intense) and quite probably suffering from dementia, either environmental or inherited.

He was also burdened with chronic physical injuries, incurred in multiple serious accidents over his long life.
And Hemingway did not drink himself to death, though I suppose he could have, given the time--but he used a shotgun.
I should say that a fair number of respected writers lived long and perhaps happy lives.
