Should we take the last line of #147 as "at random from the truth" (l.12), or as evidence of recovery?

Who is the "thy" of l. 14 in #148?

Why does the poet think his beloved loves others (#149, l. 14)?

Is the beloved the sort of person likely to be moved by the argument in ll. 11-14 of #150?

In #151, l.5 is sometimes punctuated with a comma after "For," as well as after "me," changing the meaning. Which meaning suits the context of this poem better?

Does #152 seem final? Why or why not?
