【Ashamed】 , 【Mortified】 and 【Chagrined】 all mean acutely or manifestly conscious of embarrassment and humiliation.

One is 【ashamed】 whose embarrassment and humiliation are mixed sometimes with a sense of guilt and always with the awareness of being discredited or disgraced by one′s own or vicariously another′s shameful or indecorous act, behavior, or situation.

• he sees he has nothing to be 【ashamed】 of in you—rather everything to be proud of
  —Meredith
• Suddenly Joe began to cry. He was 【ashamed】 and did not want his wife to see
  —Anderson

One is also 【ashamed】 who by anticipating such feelings is reluctant or unwilling to do something that seems shameful.

• what shall I do? for my lord taketh away from me the stewardship: I cannot dig; to beg I am 【ashamed】
  —Lk 16:3

One is 【mortified】 whose embarrassment and humiliation are mixed with a strong sense of being put in a false or disagreeable light and who suffers more because of loss of esteem or a hurt to his own pride than because of the shameful or indecorous character of the act, behavior, or situation; thus, one might say that the boy was not 【ashamed】 of his conduct (because he did not consider it wrong) but he was 【mortified】 when he was suspended from the team (because others viewed his conduct in a light that resulted in injury to his pride and position).

• "Don′t spare him; let the university expel him! . . . Let Robert be 【ashamed】 , if you would save his soul alive!" . . . Robert was sullen and 【mortified】 , but, alas, not 【ashamed】
  —Deland

One is 【chagrined】 whose embarrassment and humiliation are accompanied by vexation or annoyance.

• Tony, somewhat 【chagrined】 at his mistake, said he should like to see the other pictures
  —Archibald Marshall
• I was as much 【chagrined】 as they were flabbergasted by this involuntary outbreak
  —L. P. Smith
