Alanon/naranon are meetings held, usually in churches or halls, after hours.
It's kinda like AA, only for friends and family of the A. Lots of support, shared experiences, and knowledge. They also work a 12 step program similar to AA. Only ours deal more with codependency.
Hope you find one in your area. It will help you so much to be with others who are going through similar crisis.
Hugs,
