How can I then return in happy plight (Sonnet 28)

How can I then return in happy plight,
That am debarr’d the benefit of rest?
When day’s oppression is not eased by night,
But day by night, and night by day, oppress’d?
And each, though enemies to either’s reign,
Do in consent shake hands to torture me;
The one by toil, the other to complain
How far I toil, still farther off from thee.
I tell the day, to please him thou art bright
And dost him grace when clouds do blot the heaven:
So flatter I the swart-complexion’d night,
When sparkling stars twire not thou gild’st the even
     But day doth daily draw my sorrows longer
     And night doth nightly make grief’s strength seem stronger.
