The open question the colors every aspect of Woolf's Mrs. Dalloway

Nearing the end of Virginia Woolf’s fantastic and challenging novel Mrs. Dalloway (1925) I’m thinking of the major characters in the novel and their interceptions and inter-relationships, as each navigates the streets of London over the course of a single bright, sunny day: Clarissa Dalloway, preparing for an evening party at her home, concerned with being perceived as trivial – is playing hostess all her life amounts to?; Peter Walsh, at one time in love with Clarissa, now suddenly turns up in London after a long absence in India announcing he’s there to get legal council and to divorce his wife and marry (presumably) his new crush – his life a wreck and a waste, and would he have been better off had hem married Clarissa; her husband, mostly absent, busy w/ government work of some sort – is he involved with someone else as well? – yet despite his coldness and lack of originality and spark at least doing some good in his government work; Hugh (?), a lightweight who’s drawn to some kind of Buckingham Palace job and called upon to write an elegantly crafted but essentially stupid letter to the Times; most of all: Septimus Smith, suffering from what today we know as PTSD, after seeing close friend killed in the war, begin cared for by his devoted “war bride,” Rezia, but becoming over the course of the day – plagued by visits to 2 doctors, who have completely opposite treatment proposals – sinking ever more deeply into depression, delusion, and suicidal ideation. Of all the characters, he seems to be the only one whose social circle doesn’t intersect w/ Clarissa’s (although maybe that will happen by the end, perhaps through his high-priced physician?). An open question remains: To what extent are the two polar opposite characters – perfect host Mrs. Dalloway and suicidal Spetimus – different poles in Woolf’s own personality (sadly, we cannot read of Septimus’s suicidal thoughts w/out thinking of Woolf’s death), or even two opposite poles in British society of her era:
