Note: Statistics cannot be used to predict the course of individual lives. They can be used as a risk guide, but they do not evaluate any one person's case. Any statement about risk is done on an actuarial basis in a similar way insurance companies compile lists of features about people at risk for automobile accidents.

A Christian support group committed to ministering to the spiritual, emotional, and physical needs of individuals and families affected by mental illness. Within an atmosphere of acceptance, compassion, and empathy we offer relevant information, and trustworthy resources related to issues commonly associated with and experienced by those who have a loved one affected by a neurological disorder or a chemical imbalance. We provide a place to share one’s faith in God and one’s personal experiences as we walk a similar path alongside a family member, friend, or loved one living with a serious mental illness.
