Find a family to family group in your area, this 13 weeks class truly helped me understand and cope with my husbands condition. This is a safe place to talk about mental illness. One of my biggest issues was not being able to talk about it with anyone because you don’t want to break your loved one’s trust. This is an amazing class where you learn about different mental illnesses, medications, how the brain works, on top of meeting great people. Definitely recommend this to anyone who has any family member suffering.
