Peer support is support offered by someone who has lived through mental health challenges, substance use, or both, and who has been trained — and in most settings, certified — to use that lived experience to help other people in their own recovery.
The core of peer support is simple: it's help from someone who has actually been there. A peer specialist isn't working from a textbook description of what depression or addiction feels like — they know it from the inside, and they've built a life on the other side of it. That shared understanding creates a kind of trust and connection that's different from — not better or worse than, just different from — what you get from a clinician.
Peer support is a recognized, evidence-informed part of the mental health and substance use care system. It's covered by Medicaid in many states, including New Hampshire, and is increasingly built into community mental health center (CMHC) teams, hospital discharge planning, and recovery community organizations.
