Hang in there...I wish it my AS would decide to go to treatment so quickly...I hope she means it this time. All we can really do is give them the option to get help, and try to learn to take care of ourselves.
I think we get so used to the chaos that we really do forget how to live our own lives, it's a hard hard thing..having a child as an addict. Just know you are not alone...I feel your pain..
