Hi there,
I am so sorry to hear of your daughters addictions! I am a recovering addict and alcoholoc myself. I also have a father who is an alcoholic and being that I am in recovery I deal with many adidicts and alcoholics everday. Most of them are in a program and sober.
As far the relationship with your daughter goes, I have to say that when my Mom would try to deal with me whiel I was practicing in my addictions she had to learn to set her own boundries. and to stick to them. Now that I am sober and clean I realize how difficult and emorional it was for her to do so.
I think the key thing to remeraber would be to keep yourself safe. Set a boundri of how much you are willing to deal with. Sticking to that is the part that is difficult and takes work. If this means you need to let your daughter go for whiel only you can be the one to answer this question. My mother learned the hard way and she did some enableing with me and at a certain point she wised up and stopped doing this! It would only cause her and I harm when it was done.
I will say a prayer for the both of you. And as another suggested...al-anon is a wonderful place to go to seek support from other men and women who have already experienced these things.
Please forgive my tyoing as I just had neck surgery a few days agao and it is hard to see every word I type.
Hang in there and best of luck!
Chrissy
