Welcome to SR!
I'm both an RA (recovering addict - crack) and someone who has loved ones who are addicts. I've had to work on recovery from both my addiction AND codependence at the same time.
I do hope you check out the Friends/Family forum. They have been an invaluable source of support for me. I was fortunate to have a family who let me fall on my face, with my addiction, and find my way back up. I will forever be grateful.
Hugs and prayers!
Amy
