Having lost everything, including her only son, Marcy is overcome with bitter grief. It manifests primarily as anger: A mixture of various emotions, including furious, unrelenting hatred towards raiders, paranoia and excessive caution (in fact, she is reluctant to settle in any permanent area, due to fear of it being overrun again), and irritation. It takes a great deal to improve her spirits, but even then, the string of bad fortune and losing her only child has left her permanently scarred.
