Postpartum depressed women suffer from functional impairment in their mood, thoughts, cognition and physical well being leading to poor motivation, bonding difficulties, decreased productivity, conflict and neglect. Moderate/ severe depression responds best to a combination of antidepressants and counseling. This study will estimate the proportion of women who return to functionality after treatment with Desvenlafaxine and examine the differential impact of change in depression and anxiety symptoms on functionality over twelve weeks. Depression and anxiety symptoms will be monitored through six mood questionnaires; functional recovery will be monitored through a simple self-report questionnaire at each visit.
