When in disgrace with fortune and men's eyes
men's eyes=in the eyes of men
I all alone beweep my outcast state,
beweep=deplore
outcast state - as a gay person
And trouble deaf heaven with my bootless cries,
bootless=unsuccessful (bootless is from Old English bot, "advantage, profit," + -less, from Old English leas, "without.")
And look upon myself, and curse my fate,
Wishing me like to one more rich in hope,
Featured like him, like him with friends possessed,
Desiring this man's art, and that man's scope,
With what I most enjoy contented least;
what I most enjoy=sex
Yet in these thoughts my self almost despising,
Haply I think on thee, and then my state,
haply=by accident, unexpectedly
state=state of mind
Like to the lark at break of day arising
From sullen earth, sings hymns at heaven's gate;
sullen=darkened by clouds
For thy sweet love remembered such wealth brings
That then I scorn to change my state with kings.
change=exchange
kings=kings'
