What are the motifs in Look Back in Anger by John Osborne?

Identity Crisis is a recurring idea. While Jimmy harangues everyone around him to open themselves to honest feeling, he is trapped in his own problems of social identity. He doesn't seem to fit in anywhere. As Colonel Redfern points out, operating a sweet-stall seems an odd occupation for an educated young man. Jimmy sees suffering the pain of life as the only way to find, or "earn," one's true identity. Alison does finally suffer the immeasurable loss of her unborn child and comes back to Jimmy, who seems to embrace her. Helena discovers that she can be happy only if she lives according to her perceived principles of right and wrong.
