Al-Anon is a long-standing self-help organization for family members and friends of people who have alcohol and drug use problems. Al-Anon is based on the steps and principles of Alcoholics Anonymous (AA).
The message of Al-Anon for family members is that:
You are valuable and need to take care of yourself.
You are not responsible for the person who is using alcohol or drugs.
You shouldn't make threats that you don't intend to keep.
