Shakespeare's Sonnets: How can I then return in happy plight

How can I then return in happy plightThat am debarr'd the benefit of rest?When day's oppression is not eas'd by night,But day by night and night by day oppress't.And each (though enemies to either's reign)Do in consent shake hands to torture me,The one by toil, the other to complainHow far I toil, still farther off from thee,I tell the day to please him thou art brightAnd dost him grace when clouds do blot the heav'n:So flatter I the swart-complexion'd night,When sparkling stars twire not thou guil'st the h eav'n. But day doth daily draw my sorrows longer, And night doth nightly make grief's length seem stronger.
