Anxiety and Depression Association of America (ADAA)

ADAA maintains four separate peer-led online communities dedicated to anxiety disorders, depression, PTSD, and obsessive-compulsive disorder, each with active forums where members ask questions and share experiences without therapist moderation. The approach is purely peer-to-peer, allowing candid conversations and practical advice grounded in lived experience, all available at no cost.

Best for those seeking free, moderated-but-not-clinician communities where you can speak openly with others managing similar mental health conditions. The disorder-specific communities help you find the right group, though the peer-only model means no clinical guidance if conversations require it.
