What is exactly peer support? Peer support was designed to fill in the gaps in our mental health support system. It is not an replacement of therapy, or any form of medical profession. Peer support is a way to share our story and knowing that there are others around us that have gone through a similar story. Peer support isn’t about dishing every detail of our own mental health challenges, it’s about the ability to lend a hand, a listening ear and a compassionate heart .
