Brief  Introduction

(Adeline) Virginia Woolf (née Stephen; 25 January 1882 – 28 March 1941) was an English novelist and essayist, regarded as one of the foremost modernist literary figures of the twentieth century.During the interwar period, Woolf was a significant figure in London literary society and a member of the Bloomsbury Group. Her most famous works include the novels Mrs Dalloway (1925), To the Lighthouse (1927) and Orlando (1928), and the book-length essay A Room of One's Own (1929), with its famous dictum, "a woman must have money and a room of her own if she is to write fiction."

Main  body

My dear,

'Dearest, I feel certain I am going mad again. I feel we can't go through another of those terrible times. And I shan't recover this time. I begin to hear voices, and I can't concentrate. So I am doing what seems the best thing to do. You have given me the greatest possible happiness. You have been in every way all that anyone could be. I don't think two people could have been happier till this terrible disease came. I can't fight any longer. I know that I am spoiling your life, that without me you could work. And you will I know. You see I can't even write this properly. I can't read. What I want to say is I owe all the happiness of my life to you. You have been entirely patient with me and incredibly good. I want to say that - everybody knows it. If anybody could have saved me it would have been you. Everything has gone from me but the certainty of your goodness. I can't go on spoiling your life any longer.
