Hi twentyquid
I don't have much experience to share with you, except to say I empathise with feeling useless and helpless when someone you love goes off the rails.
I hope you'll visit our Family and Friends forums as well as this one.
Friends and Family of Substance Abusers - SoberRecovery : Alcoholism Drug Addiction Help and Information Friends and Family of Alcoholics - SoberRecovery : Alcoholism Drug Addiction Help and Information
You'll find a lot of hope and support here on SR
Welcome
