That was a beautiful testament to your daughter. I am glad that you find comfort in this site. I do too. I have a 25 YO AS (addicted son) whom I have limited contact with. I basically had the same conversation with him that you did. If my son continues to use drugs and alcohol, I've got nothing for him. However, if he chooses to get help for that problem then I will help him in any way that I can. So he's pretty distant from me and most of the time does not return my phone calls. But that's okay. I know enough about this disease to not take that personally.
I'm glad you're also going to Alanon, reading books, etc. Keep coming back, because I bet you've got ESH (experience, strength, hope) to share with the "real" newbies and also because this is a great place for when you are looking for the same.
