Centered on "MindSailing," this 4-week guided self-help recovery journey is designed for potential and mild-to-moderate bulimia nervosa patients. Through a journey guide and a mobile app, we provide a sustainable and accessible recovery experience, aiming for self-exploration and breakthroughs. The journey includes regular remote psychological consultations for critical guidance and integrates innovative AR interaction and CBT therapy. Users engage with daily CBT mindfulness cards and wish gacha machines to gradually disconnect from symptoms and regain healthy autonomy. We believe this guided self-help approach offers deeper support, guiding patients to a healthier, more confident future.
