I feel that Sonnet 140 is more plea than warning. I think the Id is more prominent here in his begging the oop to be kind to him. In line 3 he says Lest sorrow lend me words, and words express / The manner of my pity-wanting pain. Both sorrow and pity-wanting are more depressed, or just feeling sorry for oneself, than they are like anger or reproachfulness. When he talks about going mad, I think it's more of depression or even aging and senility as described in line 7,8, and 9. As testy sick men when their deaths be near / No news but health from their physicians know / For if I should despair I should grow mad.
Right now I'm not sure what to make of number 149. This definitely feels like a struggle, but is it an internal struggle maybe? Line 2 describes him turning against himself: When I against myself with thee partake? Other than that, it seems like he wishes he was not as addicted to, or in love with, the oop. So, my take on Freud leads me to believe that this is the superego and the id doing a subtle but consequential domination dance.
Sonnet 152 definitely has a lot more anger, I think that implies the id. Not only anger towards the oop, but angry at his own ignorance. For I have sworn deep oaths of thy deep kindness, / Oaths of thy love, thy truth, thy constancy / And to enlighten thee gave eyes to blindness, / Or made them swear against the thing they see. He was fooling himself.
