A 28-year-old female is brought to the ER by her husband because of bizarre behavior 4 days after the uncomplicated delivery of a full-term healthy boy. Her personal and family history of mental illness is negative. The second day after delivery, she accused her husband of poisoning her food. She has problems falling asleep, generally sleeping only 2-3 hours nightly and complaining of unpleasant smells waking her up.

She would stop the ongoing activity from time to time with a blank expression and was found several times staring at the wall and silently counting.

She feels guilty about being a terrible mother and states that she did not deserve to have a baby. The morning when her husband asked for your advice, she told him that she hears voices telling her to take her son and jump out the window. What is the most likely diagnosis?
