I cannot sleep—my nights glide on <br /> <br /> In one unbroken thought of thee; <br /> <br />And when the gloomy shades are gone, <br /> <br /> I start the dawning light to see. <br /> <br />And as I watch the rising morn <br /> <br /> Gain slowly o'er the yielding sky, <br /> <br />And mark another day new born, <br /> <br /> That glows so brightly—yet must die— <br /> <br />I think how all the hopes we cherish <br /> <br /> As transient, though as bright, will be; <br /> <br />And frailest of the hopes that perish <br /> <br /> Were mine, that told of love and thee!<br /><br />Louisa Stuart Costello<br /><br />http://www.poemhunter.com/poem/lines-i-cannot-sleep/
