I am a codie (codependent), so I feel I am in codie recovery as well as addiction recovery (crack).
As Dee said, there is a forum for friends/family of substance abusers, and there are a lot of people over there going through similar situations.
It sounds like you are doing the right things, but I know it's still hard. Addiction is a family disease, and anyone who loves an addict is affected in some way.
Many people find help in al-anon, no matter what substance their A (addict) uses, and maybe you can find a meeting.
Whether you find a meeting or not, the support here is awesome and we're here 24/7.
Hugs and prayers!
