Fernando Pessoa said this quote

And leaning on the windowsill to enjoy the day, gazing at the variegated mass of the whole city, just one thought fills my soul: that I profoundly wish to die, to cease, to see no more light shining on this city or any city, to think no more, to feel no more, to leave behind the march of time and the sun like a piece of wrapping paper, to remove like a heavy suit – next to the big bed – the involuntary effort of being.
