This study explores the potential of integrating virtual reality (VR) metaverse environments and personalized AI assistants to support the mental health of women experiencing postpartum depression. Employing a user-centered mixed-methods research design, the study investigates the factors contributing to postpartum depression, the applications of VR in mental health therapy, the role of AI in providing mental health support, and the impact of VR metaverse communities on mental well-being. Based on user research insights, a VR metaverse concept with multiple interactive modules and an AI avatar assistant is proposed to provide a supportive and immersive healing environment. A questionnaire evaluation of the design concept reveals positive user feedback and acceptance, highlighting the potential of VR and AI technologies in addressing the mental health challenges postpartum women face. The study discusses limitations, future improvements, and the importance of technological advancements in catering to maternal mental health needs.
