I understand completely what you are going through.
I don't know any GA rehabs, but there is a nice one in South Florida called The Watershed. The really work on you and you can transition from the main facility into an apartment type living. i stayed a total of 3 months. My addiction was so tough, I didn't want to go to group or talk or work on me, but the staff wouldn't give up on me, and I am grateful. Best wishes, you can do this.
