In "Death of a Salesman," how does Willy handle the reality of the money he has earned when Linda figures out his commission?

Willy is forced to admit that he didn't sell as much as he had initially indicated, but he insists, "I'll knock 'em dead next week. I'll go to Hartford. I'm very well liked in Hartford. You know ... people don't seem to take to me." His comments are typical of Willy's contradictions. Linda as usual reassures him that he's "doing wonderful." 

But then he laments that he's "fat... very foolish to look at," and he reveals that he had "cracked" a salesman "across the face" because he thinks the man had called Willy a "walrus." He believes that people laugh at him; his evident paranoia and belligerence show us that he is insecure. Linda again bolsters his self-esteem by telling him he's "the handsomest man in the world." His concern about money seems to be swept aside by her constant reassurances.
