How can in-person support groups help me cope with mental illness?

Whether the in-person support group is led by a therapist or is a peer-support model, either can be good for you in multiple ways. First, they get you out of the house and around others. Second, they give you a chance to get support and understanding for what you are going through from people who know about it firsthand. Generally, you are not required to share, especially if it's your first time. So, just sit back, listen, and learn what it is all about.
